[0022] Please refer to Figure 1 This document illustrates a flowchart of a method for determining a radionuclide intake dose according to an embodiment of this application. Specifically, this method for determining the radionuclide intake dose may include: Step 101: Obtain information on radionuclide atmospheric deposition, plant information, rainfall information, feed type information, and feed usage information within the area to be evaluated.

[0023] Step 102: Based on the radionuclide atmospheric deposition information, plant information and rainfall information, obtain the plant activity concentration using a preset plant activity concentration algorithm.

[0024] Step 103: Based on the plant activity concentration, feed type information, and feed usage information, obtain the animal activity concentration using a preset animal activity concentration algorithm.

[0025] Step 104: Based on the preset food processing coefficient, preset decay rate, and the animal activity concentration, obtain the food activity concentration using a preset food activity concentration algorithm.

[0026] Step 105: Based on the preset food consumption rate, preset intake dose factor, and the food activity concentration, determine the human body's radionuclide intake dose using a preset radionuclide intake dose algorithm.

[0027] It should be noted that the area to be assessed may include the area surrounding nuclear power plants, the area surrounding other nuclear facilities, etc.

[0028] It should be noted that the nuclides may include 131I, 90Sr, 137Cs and 134Cs, etc.

[0029] It should be noted that plants and animals can include representative plant and animal products from the area to be assessed. An average food list for the area can be determined by analyzing the food consumption habits of the population near the area, and information on representative plant and animal products can then be obtained based on this average food list.

[0030] In this way, by acquiring information on radionuclide atmospheric deposition, plant information, rainfall information, feed type information, and feed usage information within the area to be evaluated, plant activity concentration can be obtained using a preset plant activity concentration algorithm based on the radionuclide atmospheric deposition information, plant information, and rainfall information. Animal activity concentration can be obtained using a preset animal activity concentration algorithm based on the plant activity concentration, feed type information, and feed usage information. Food activity concentration can be obtained using a preset food activity concentration algorithm based on preset food processing coefficients, preset decay rates, and the animal activity concentration. Human radionuclide intake dose can be determined using a preset radionuclide intake dose algorithm based on preset food consumption rates, preset intake dose factors, and the food activity concentration. Since the radionuclide transfer behavior in the terrestrial ecosystem can be simulated based on the acquired information on radionuclide atmospheric deposition, plant information, rainfall information, feed type information, and feed usage information within the area to be evaluated, the effective dose of radionuclides to humans through the food chain can be calculated, thus improving the reliability of the assessment of radionuclide intake dose for the human population within the area to be evaluated.

[0031] Optionally, in one possible implementation of this embodiment, in step 102, firstly, based on a preset plant growth rate, a preset retention coefficient, the rainfall information, and the plant information, a preset deposition algorithm is used to determine the amount of nuclide plant deposition. Secondly, based on a preset decay rate, a preset transfer coefficient, the amount of nuclide plant deposition, the plant information, and the rainfall information, the leaf activity concentration is calculated. Thirdly, based on a preset decay rate, a preset nuclide fixation rate, a preset nuclide leaching rate, a preset plant translocation factor, and the plant information, the root activity concentration is calculated. Finally, based on the leaf activity concentration and the root activity concentration, the plant activity concentration is obtained.

[0032] In this implementation, the radionuclide atmospheric deposition information may include atmospheric dry deposition amount and atmospheric wet deposition amount.

[0033] In a specific implementation of this method, firstly, plant biomass can be calculated based on a preset plant growth rate and the plant information. Secondly, a first retention factor can be calculated based on the plant biomass and the leaf interception constant. Thirdly, a second retention factor can be calculated based on a preset retention coefficient and the rainfall information. Finally, the amount of radionuclide plant deposition can be determined based on atmospheric dry deposition, the first retention factor, atmospheric wet deposition, and the second retention factor.

[0034] In this specific implementation, the plant information may include plant yield, initial dry weight, and harvest dry weight. Initial dry weight can be the dry weight at the initial stage of plant growth. Harvest dry weight can be the dry weight at the harvest stage.

[0035] In this specific implementation, the preset plant growth rate can be the plant's growth rate constant. The preset plant growth rate is determined according to the plant species. For example, winter wheat growth is divided into two growth periods: the overwintering period and the following year's growth period. Its preset plant growth rates can be 0.08 per day and 0.12 per day, respectively.

[0036] In one specific implementation, the plant biomass is calculated based on a preset plant growth rate, initial plant dry weight, and harvested plant dry weight. It can be shown in formula (1): (1) in, The initial dry weight of plant i. For the dry weight of plant i at harvest, The preset plant growth rate for plant i. For time Plant biomass at that time.

[0037] It is understandable that plant biomass can be considered as time-dependent biomass of plants.

[0038] Furthermore, here, It can be obtained directly. It can also be the ratio of plant yield to a preset harvest ratio. The preset harvest ratio can be the ratio of edible dry weight to total dry weight at harvest. Here, total dry weight can be the dry weight of the plant at the harvest stage.

[0039] In this specific implementation, here, the first cutoff factor It can be a dry sedimentation cutoff factor. This dry sedimentation cutoff factor can be estimated based on the plant biomass at the time of deposition.

[0040] Another specific implementation involves calculating the first retention factor based on the plant biomass and leaf interception constant. It can be shown in formula (2): (2) in, For time Plant biomass at that time This represents the leaf interception constant. Here, the leaf interception constant can be determined based on the plant species.

[0041] In this specific implementation, rainfall information may include rainfall amount.

[0042] In this specific implementation process, the second cutoff factor It can be the wet sedimentation cutoff factor. The calculation of the wet sedimentation cutoff factor is similar to that of the dry sedimentation. The wet sedimentation cutoff factor increases proportionally with the leaf area index (LAI) and decreases with the amount of rainfall, as shown in formula (3), where LAI is replaced by plant biomass.

[0043] Another specific implementation method involves calculating the second retention factor based on a preset retention coefficient and rainfall amount. It can be shown in formula (3): (3) in, For time Plant biomass at that time The preset retention coefficient for plant i, This refers to rainfall.

[0044] Preferably, the preset retention coefficient can be determined according to the plant type-nucleus-retention coefficient relationship table.

[0045] For example, the relationship between the retention coefficients of different plants and elements can be shown in Table 1: Table 1:

[0046] Understandably, the accumulation of water film on plant leaves during rainfall is considered when calculating the wet deposition retention factor. For cases with low rainfall and fully developed plant canopies, the second retention factor... It may be greater than 1.0, in which case the second cutoff factor... The value can be 1.0.

[0047] Another specific implementation method involves determining the amount of nucleophyte deposition based on atmospheric dry deposition and the first cutoff factor, atmospheric wet deposition, and the second cutoff factor. It can be shown in formula (4): (4) in, This can be the amount of nucleoside deposition in plant i. This represents atmospheric dry sedimentation. As the first cutoff factor, This represents atmospheric wet deposition. This is the second cutoff factor.

[0048] It is understandable that deposition on plants is the result of the interaction of meteorological conditions, the chemical and physical properties of pollutants, and the characteristics of the plant canopy. The total amount of deposition on plants can be the sum of dry and wet deposition, and can be calculated using formula (4).

[0049] In another specific implementation of this method, firstly, the plant type can be determined based on the plant information. Secondly, in response to the plant type being a fully edible plant, a rainfall correction factor corresponding to the plant is determined based on the rainfall information; the leaf activity concentration is calculated based on the preset decay rate, rainfall correction factor, nuclide plant deposition amount, and plant information; or, in response to the plant type being a partially edible plant, the leaf activity concentration is calculated based on the preset decay rate, preset transfer coefficient, nuclide plant deposition amount, and plant information.

[0050] In this specific implementation, plant information may also include plant type. Plant type may include fully edible plants and partially edible plants. Rainfall information may also include the time between deposition and the first rainfall.

[0051] In this specific implementation, the preset decay rate may include a preset weathering decay rate, a preset growth dilution decay rate, and a preset radiation decay rate.

[0052] In one specific implementation, when the plant type is determined to be a completely edible plant, a rainfall correction factor corresponding to the plant is determined based on the time between the deposition and the first rainfall, as shown in formula (5): (5) in, It can be a rainfall correction factor for plants. This can be the time between deposition and the first rainfall.

[0053] Furthermore, the leaf activity concentration can be calculated based on preset weathering decay rate, preset growth dilution decay rate, preset radiation decay rate, rainfall correction factor, nuclide plant deposition amount, and plant yield, as shown in formula (6): (6) in, This can be used for plants that are entirely edible, specifically the leaf activity concentration of plant i at time t. It can be a rainfall correction factor for plants. , The decay rate can be preset. A preset weathering and decay rate can be set. The growth, dilution, and decay rates can be preset. It can be a preset radiative decay rate. This can be the amount of nucleoside deposition in plant i. This can be the plant yield of plant i.

[0054] Here, for example, the rainfall correction factor m is a correction factor for the weathering rate of early rainfall. If the time interval is more than 5 days (120 hours), the effect of rainfall can be ignored (m is set to 1). For the time h between deposition and the first rainfall, which ranges from 1 to 120 hours, m can be 1 if h is greater than 120 hours.

[0055] In one specific implementation, when the plant type is determined to be a partially edible plant, the leaf activity concentration can be calculated based on a preset radiation decay rate, a preset transfer coefficient, the amount of nuclide deposited in the plant, and the plant yield, as shown in formula (7): (7) in, This can be used to determine the leaf activity concentration of plant i at time t, assuming the plant type is partially edible. It can be a preset transfer coefficient, that is, the transfer coefficient of the nuclide from the leaf to the edible part at time t. It can be a preset radiative decay rate. This can be the amount of nucleoside deposition in plant i. This can be the plant yield of plant i.

[0056] It is understandable that radionuclides deposited on plants will be removed from plant leaves through weathering, growth dilution, and translocation processes. For fully edible plants, leaf activity concentration can be calculated using an exponential function, as shown in Equation (6). For partially edible plants, leaf activity concentration can be calculated using a translocation factor equation, as shown in Equation (7).

[0057] In this implementation, plant information may further include the amount of plant-related nuclides deposited in the soil, soil depth, and soil density. The preset plant translocation factor can be a soil-to-plant translocation factor.

[0058] In another specific implementation of this method, the root activity concentration can be calculated based on preset radiation decay rate, preset nuclide fixation rate, preset nuclide leaching rate, preset plant translocation factor, nuclide soil deposition amount, soil depth and soil density, as shown in formula (8): (8) in, This can be the root activity concentration of plant i at time t. It can be a preset plant transport factor, The preset nuclide leaching rate can be set. A fixed rate can be set for a preset nuclide. It can be a preset radiative decay rate. It can be used to measure the amount of radionuclides deposited in soil. It can be based on soil depth, It can be soil density.

[0059] For example, in soils with low organic matter content and low cation exchange capacity, the preset nuclide fixation rate can be 0. The soil depth for grass crops is 10 cm, and for other crops (including trees) it is 20 cm. The soil density can be 1.25 × 10³ kg / m³.

[0060] In another specific implementation of this method, the plant activity concentration is calculated based on the leaf activity concentration and root activity concentration, as shown in formula (9): (9) in, This can be the plant activity concentration of plant i at time t. This refers to the leaf activity concentration of the plant at time t, assuming the plant type is either fully edible or partially edible. It can be the root activity concentration of plant i at time t.

[0061] In this way, the accuracy of plant activity concentration can be further improved by first determining the total amount of plant sediment, then calculating the leaf activity concentration and root activity concentration based on the total amount of plant sediment, and then calculating the plant activity concentration based on the leaf activity concentration and root activity concentration.

[0062] Optionally, in one possible implementation of this embodiment, in step 103, firstly, the animal activity ingestion rate can be calculated based on the plant activity concentration, feed type information, and feed usage information. Secondly, the animal activity concentration can be obtained based on a preset biotransport rate, a preset transport rate ratio, a preset animal transport factor, a preset decay rate, and the animal activity ingestion rate.

[0063] In this implementation, feed usage information may include the amount of feed given. Feed type information may include the number of different types of feed given. Here, the feed may be plant-based feed.

[0064] In a specific implementation of this method, the animal activity intake rate is calculated based on the plant activity concentration, feed type information, and feed amount, as shown in formula (10): (10) in, This can be the animal activity ingestion rate of animal m. It can be the concentration of plant activity. This can be used to determine the amount of feed that animal m should be given to feed i. The number of types of feed that can be fed to animal m.

[0065] In another specific implementation of this method, the animal activity concentration is calculated based on a preset biotransport rate, a preset transport rate ratio, a preset radiation decay rate, a preset animal transport factor, and the animal activity uptake rate, as shown in formula (11): (11) in, This can be the animal activity concentration of animal m at time t. This can be the animal activity ingestion rate of animal m. It can be a preset animal transport factor, It can be a preset transfer rate ratio. It can be preset to the biotransport rate. It can be a preset radiative decay rate. It can be the number of biological transport rates.

[0066] Understandably, here, the preset biotransport rate... This can be the transport factor for animal m at time t. Preset biotransport rate. This can be the biological transport rate of animal m to transport rate j. A preset transport rate ratio. It can be the proportion of the biological transport rate j.

[0067] In this way, the animal activity ingestion rate can be calculated first based on the plant activity concentration, feed type information, and feed usage information. Then, the animal activity concentration can be calculated based on the preset biotransport rate, preset transport rate ratio, preset animal transport factor, and the animal activity ingestion rate, which can further improve the accuracy of animal activity concentration.

[0068] It should be noted that the specific implementation process provided in this embodiment can be combined with various specific implementation processes provided in the foregoing implementation methods to realize the method for determining the radionuclide intake dose in this embodiment. Detailed descriptions can be found in the relevant content of the foregoing implementation methods, and will not be repeated here.

[0069] Optionally, in one possible implementation of this embodiment, in step 104, firstly, the storage and processing time of the food can be obtained. Secondly, based on the storage and processing time of the food, a preset food processing coefficient, a preset decay rate, and animal activity concentration, the food activity concentration can be obtained using a preset food activity concentration algorithm.

[0070] In this implementation, the animal activity concentration can be used as the activity concentration of the food raw material. The preset decay rate can include a preset radiation decay rate.

[0071] In a specific implementation of this method, based on the storage and processing time of the food, a preset food processing coefficient, a preset decay rate, and animal activity concentration, the food activity concentration is calculated using a preset food activity concentration algorithm, as shown in formula (12): (12) in, We can determine the activity concentration of product k to be consumed at time t, i.e., the food activity concentration. This can be the activity concentration in the raw material product k at time t, i.e., the animal activity concentration. It can be used for storage and processing time, The food processing coefficient can be preset. It can be a preset radiation decay rate, i.e., a radioactive decay constant.

[0072] Understandably, when calculating contamination in human food, the enrichment or dilution of activity during processing and cooking, as well as processing and storage time, are taken into account. The activity concentration in product k (food) is calculated from the raw material product using formula (12).

[0073] In this way, a more accurate and effective food activity concentration can be calculated based on the food's storage and processing time, a preset food processing coefficient, a preset decay rate, and animal activity concentration, using a preset food activity concentration algorithm, so as to improve the accuracy of subsequent human intake dose calculation.

[0074] It should be noted that the specific implementation process provided in this embodiment can be combined with various specific implementation processes provided in the foregoing implementation methods to realize the method for determining the radionuclide intake dose in this embodiment. Detailed descriptions can be found in the relevant content of the foregoing implementation methods, and will not be repeated here.

[0075] Optionally, in one possible implementation of this embodiment, in step 105, firstly, the human activity intake rate is calculated based on a preset food consumption rate and the food activity concentration. Secondly, the human nuclide intake dose can be obtained based on the human activity intake rate and a preset intake dose factor.

[0076] In a specific implementation of this method, the human activity intake rate is calculated based on the preset food consumption rate and the food activity concentration, as shown in formula (13): (13) in, It can be used to measure the rate of human activity intake. It can be used to determine the activity concentration of food (k). It can be the consumption rate of food k, that is, the preset food consumption rate.

[0077] In this implementation, the preset intake dose factor can be based on age. The preset intake dose factor can be found in ICIRP Publication No. 30 (ICRP 1979).

[0078] In another specific implementation of this method, the radionuclide intake dose of the human body is calculated based on the human activity intake rate and the preset intake dose factor, as shown in formula (14): (14) in, It can be used as the dose of radionuclides ingested by the human body. It can be used to measure the rate of human activity intake. It can be a preset intake dose factor.

[0079] Understandably, this can take into account the dietary habits of different age groups and the resulting dose from consuming contaminated food within time T after deposition. It can be calculated using formula (14).

[0080] In this way, the human body's activity intake rate can be calculated first based on the preset food consumption rate and the food activity concentration, and then the human body's radionuclide intake dose can be calculated based on the human body's activity intake rate and the preset intake dose factor, which can further improve the accuracy of the human body's radionuclide intake dose.

[0081] Moreover, by simulating the transfer behavior of radionuclides in the food chain (plant / animal products - humans), and taking into account all relevant transfer processes between soil, plants, animals and processed products in the actual area to be evaluated for the ingestion route, such as interception, translocation, root absorption, animal feeding, food processing, etc., the dose of radionuclides entering the human body through the food chain of a specific population around the area to be evaluated can be more precisely determined.

[0082] It should be noted that the specific implementation process provided in this embodiment can be combined with various specific implementation processes provided in the foregoing implementation methods to realize the method for determining the radionuclide intake dose in this embodiment. Detailed descriptions can be found in the relevant content of the foregoing implementation methods, and will not be repeated here.
