Description

Technical Field

[0003] The selected organisms typically include amphibians, a transitional type of vertebrate from aquatic to terrestrial, possessing dual characteristics of both aquatic and terrestrial vertebrates and playing a crucial role in vertebrate evolution. Amphibians are also important intermediate groups in food chains and ecosystems, playing a vital role in maintaining the integrity and stability of ecosystems. Due to their limited migratory capacity, highly permeable skin, and dual aquatic and terrestrial life history, amphibians have weak resistance to environmental changes and are easily affected by changes in both aquatic and terrestrial ecological environments. Therefore, they are considered an important indicator group for environmental health and safety, and one of the key early warning indicators for monitoring environmental changes. Therefore, calculating and monitoring the radiation dose rate of amphibians is extremely important.

In current engineering calculations of biological radiation dose rates, only radiation dose rate calculation models in terrestrial ecosystems are used to calculate the radiation dose rate of amphibians.

[0038] Figure 3 This is a schematic diagram of the structure of an amphibian radiation dose rate acquisition device according to Embodiment 3 of the present invention. Detailed Implementation

[0039] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0040] Example 1:

[0041] like Figure 1 As shown, this embodiment provides a method for obtaining the radiation dose rate of amphibians, including:

[0042] Step 101: Calculate the first radiation dose rate of the amphibian in the first ecosystem and the second radiation dose rate in the second ecosystem.

[0043] Based on the living habits of amphibians, which can live both in water and on land, to ensure that the calculated radiation dose rate is consistent with reality, the corresponding radiation dose rate is calculated according to the amphibian's habitat, thereby more accurately determining the radiation impact of radioactive effluents (airborne and liquid effluents) on amphibians. In this embodiment, the first ecosystem corresponds to the terrestrial ecosystem, and the second ecosystem corresponds to the freshwater ecosystem.

[0044] Optionally, before calculating the first radiation dose rate of amphibians in the first ecosystem and the second radiation dose rate in the second ecosystem, the method further includes: obtaining the allocation results of the residence factor in the first ecosystem and the second ecosystem, wherein the residence factor satisfies the following condition:

[0045] , (1)

[0046] in, For amphibians, the factors that determine their habitation in their habitat. , , These are the retention factors on the soil surface, in the soil, and in the air of the first ecosystem. These are the residing factors in the water surface, water, bottom, and sediment of the second ecosystem, respectively.

[0047] In this embodiment, the residence factor represents the time fraction of an organism spends in different environmental media. To accurately obtain the first radiation dose rate received by amphibians in the first ecosystem and the second radiation dose rate received in the second ecosystem, it is necessary to obtain the allocation results of the residence factors of amphibians in the two ecosystems, ensuring that the sum of each residence factor is 1. The allocation ratio of the residence factors of amphibians in the first ecosystem and the second ecosystem is (…). ): ( The allocation results and ratios of the residency factor were obtained based on literature review, field observation, and other methods.

[0048] Optionally, the calculation of the first radiation dose rate of amphibians in the first ecosystem and the second radiation dose rate in the second ecosystem includes: calculating the first radiation dose rate of amphibians in the first ecosystem and the second radiation dose rate in the second ecosystem based on the allocation results of the residence factor in the first ecosystem and the second ecosystem.

[0049] The first radiation dose rate of amphibians in the first ecosystem is calculated using the following formula:

[0050] (2)

[0051] The first radiation dose rate, nuclide i In amphibians j The concentration within, in units of Bq / kg, , , They are nuclides i In amphibians j Internal radiation dose conversion factors corresponding to low-energy β, β / γ, and α, in μGy·h -1 / Bq·kg -1 , , , These are the radiation weighting factors for low-energy β, β / γ, and α, respectively. zHabitat, which includes in the soil, on the soil surface, or in the air. Amphibian organism j In habitat z residency factor nuclide i In habitat z Concentration in habitat z Medium nuclide i For amphibians j External irradiation absorbed dose rate conversion factor.

[0052] Optionally, the second radiation dose rate of amphibians in the second ecosystem can be calculated according to the following formula:

[0053] (3)

[0054] in, The second radiation dose rate, nuclide i In amphibians j The concentration within, in units of Bq / kg, , , They are nuclides i In amphibians j Internal radiation dose conversion factors corresponding to low-energy β, β / γ, and α, in μGy·h -1 / Bq·kg -1 , , , These are the radiation weighting factors for low-energy β, β / γ, and α, respectively. nuclide i Concentration in water, nuclide i Concentration in the sediment, nuclide i In amphibians j Internal external radiation dose conversion factor, , , , They are nuclides i Residual factors in water, on the surface, at the bottom, and in the sediment.

[0055] Step 102: Obtain the radiation dose rate of the amphibian based on the first radiation dose rate and the second radiation dose rate.

[0056] Specifically, obtaining the radiation dose rate of the amphibian based on the first radiation dose rate and the second radiation dose rate includes: calculating the sum of the first radiation dose rate and the second radiation dose rate; and obtaining the sum of the first radiation dose rate and the second radiation dose rate as the radiation dose rate of the amphibian.

[0057] In this embodiment, the sum of the residence factors in the calculation models of Equation (2) and Equation (3) satisfies Equation (1). Since each residence factor in Equation (1) is based on the actual residence time of amphibians in the first and second ecosystems and satisfies the sum equal to 1, substituting each residence factor in Equation (1) into Equation (2) and Equation (3) respectively yields a more accurate first radiation dose rate and second radiation dose rate. Taking the sum of the two as the final radiation dose rate result of amphibians is more accurate and consistent with the actual living environment of amphibians.

[0058] This paper uses a nuclear facility as an example to introduce methods for obtaining radiation dose rates from amphibians. Based on an ecological survey of the site, the water frog was selected as a representative amphibian. The methods for obtaining radiation dose rates from amphibians include:

[0059] Step 11: Through literature review, on-site observation, and other methods, the residence factor is obtained using formula (1). Distribution in terrestrial and freshwater ecosystems. Retention factors of the water frog. The distribution in terrestrial ecosystems and freshwater ecosystems was 0.5 and 0.5, respectively.

[0060] Step 12: Calculate the radiation dose rate of the amphibian habitat in terrestrial and freshwater ecosystems based on the allocation of the residence factor.

[0061] According to the process design of the nuclear facility, it will emit gaseous and liquid effluents. The radiation dose rate received by the water frog in the terrestrial ecosystem is calculated based on the annual emissions of the gaseous and liquid effluents.

[0062] (1) Selection of parameters

[0063] ① Allocation coefficient (Kd)

[0064] The allocation coefficient for La (lanthanum) is taken from the default value recommended by the European Community (EC). The allocation coefficients for Mo (molybdenum), Pr (praseodymium), and Tc (technetium) are all temporarily set to 0. The allocation coefficients for the other elements are taken from the values ​​in IAEA Report No. 19.

[0065] ② Concentration ratio

[0066] (a) Terrestrial ecosystems

[0067] For the element Fe (iron), for which the European Community (EC) does not provide a default concentration ratio, data from IAEA Report 479 are used; for Kr (krypton), data from EA R&D Publication 128 are used; and for Xe (xenon), since no data is available, it is temporarily set to 0. The concentration ratios for the remaining elements corresponding to different terrestrial organisms are provided by the EC-recommended values.

[0068] (b) Freshwater ecosystem

[0069] For elements Y (yttrium) and Fe (iron) for which EC recommendations do not provide default values ​​for concentration ratios, data from the IAEA .422 report are used; Mo and Pr are temporarily set to 0. Concentration ratios for other elements corresponding to different aquatic organisms are provided by EC recommendations.

[0070] ③Internal and external irradiation dose rate conversion factor

[0071] For terrestrial and freshwater ecosystems, the recommended default values ​​for the internal and external radiation dose rate conversion factor (EC) for amphibians are provided.

[0072] ④ Residency Factor

[0073] According to step 12, the sum of the residence factors of each habitat in the terrestrial ecosystem is 0.5, and the sum of the residence factors of each habitat in the freshwater ecosystem is 0.5.

[0074] (2) Calculate the dose rate of airborne and liquid effluents to the water frog.

[0075] Based on the calculation model (2) for terrestrial ecosystems and the dose rate calculation model (3) for freshwater ecosystems, the dose rates of each nuclide in the airborne and liquid effluents to the water frog were calculated to be 3.04E-03 μGy / h and 9.00E-03 μGy / h, respectively, with a total radiation dose rate of 1.20E-02 μGy / h for amphibians. The nuclide with the largest contribution was C-14, which caused a dose rate of 1.10E-02 μGy / h to the water frog. The calculation results can be used to evaluate the radiation impact of the radioactive effluents from this nuclear facility on the water frog.

[0076] The method for obtaining the radiation dose rate of amphibians in this embodiment calculates the first radiation dose rate of the amphibians in the first ecosystem and the second radiation dose rate in the second ecosystem, and then obtains the final radiation dose rate result of the amphibians by combining the two radiation dose rates. Since the first radiation dose rate and the second radiation dose rate correspond to the radiation results received by the amphibians in the two actual environmental systems, the radiation dose rate result calculated based on the first radiation dose rate and the second radiation dose rate is highly accurate. Furthermore, since each residence factor in equation (1) is based on the actual residence time of the amphibians in the first ecosystem and the second ecosystem, and satisfies the condition that the sum is equal to 1, substituting each residence factor in equation (1) into equations (2) and (3) respectively yields a more accurate first radiation dose rate and a second radiation dose rate. Taking the sum of the two as the final radiation dose rate result of the amphibians is more accurate and matches the actual living environment of the amphibians, thereby more accurately judging the radiation impact of radioactive effluents on amphibians and improving the evaluation method of the radiation impact of nuclear facilities on amphibians. The method for obtaining the radiation dose rate of amphibians in this embodiment can be understood as a detailed calculation method.

[0077] Example 2:

[0078] like Figure 2 As shown, this embodiment provides a method for obtaining the radiation dose rate of amphibians, including:

[0079] Step 201: Calculate the first radiation dose rate of the amphibian in the first ecosystem and the second radiation dose rate in the second ecosystem.

[0080] In this embodiment, the first radiation dose rate of amphibians in the first ecosystem and the second radiation dose rate in the second ecosystem are calculated based on the calculation models of equations (2) and (3) in embodiment 1, respectively. The residence factor adopts the default value of the residence factor provided by the European Community.

[0081] Step 202: Determine whether the first radiation dose rate is greater than the second radiation dose rate.

[0082] Step 203: In response to the first radiation dose rate being greater than or equal to the second radiation dose rate, the first radiation dose rate is obtained as the radiation dose rate of the amphibian; in response to the first radiation dose rate being less than the second radiation dose rate, the second radiation dose rate is obtained as the radiation dose rate of the amphibian.

[0083] In this embodiment, the allocation results of the residence factors of amphibians in terrestrial and freshwater ecosystems are ignored. The radiation dose rates of amphibians in terrestrial and freshwater ecosystems are calculated directly, and the results with larger radiation dose rates are selected for evaluation. This can improve the speed of obtaining radiation dose rates, thereby enabling a rapid and conservative assessment of the radiation impact on amphibians.

[0084] Taking a nuclear facility as an example, this paper introduces the method for obtaining radiation dose rate from amphibians. Based on the ecological survey of the site, the water frog was selected as a representative amphibian. The method for obtaining radiation dose rate from amphibians includes:

[0085] Step 21: Calculate the radiation dose rate (terrestrial ecosystem) of the radioactive effluent from the nuclear facility to the marsh frog.

[0086] According to the process design of the nuclear facility, it will emit airborne effluent. The radiation dose rate received by the marsh frog in the terrestrial ecosystem is calculated based on the annual emissions of the airborne effluent.

[0087] (1) Selection of parameters

[0088] ① Concentration ratio

[0089] For Fe, for which the European Community (EC) does not provide default values ​​for concentration ratios, data from IAEA Report 479 are used; for Kr, data from EA R&D Publication 128 are used; and for Xe, since no data is available, it is temporarily set to 0. Concentration ratios for the remaining elements and their corresponding terrestrial organisms are provided by values ​​recommended by the EC.

[0090] ②Internal and external irradiation dose rate conversion factor

[0091] The default value recommended by EC for internal and external irradiation dose rate conversion factor.

[0092] ③ Residency Factor

[0093] Terrestrial ecosystems adopt the default residency factor value recommended by EC.

[0094] (2) Calculate the dose rate of airborne effluent to the water frog.

[0095] According to the terrestrial ecosystem dose rate calculation model (i.e., formula (2) in Example 1), the dose rate of each nuclide in the airborne effluent to the marsh frog was calculated to be 3.04E-03 μGy / h. The nuclide that contributed the most was C-14, which had a dose rate of 2.15E-03 μGy / h to the marsh frog.

[0096] Step 22: Calculate the dose rate of the radioactive effluent from the nuclear facility to the marsh frog (freshwater ecosystem).

[0097] According to the process design of the nuclear facility, it will release liquid effluents into the environment. The radiation dose rate received by the water frog in the freshwater ecosystem is calculated based on the annual discharge of the liquid effluents.

[0098] (1) Selection of parameters

[0099] ① Distribution coefficient (K) d )

[0100] The allocation coefficients for element La are taken from the default values ​​recommended by EC. Mo, Pr, and Tc are all temporarily set to 0. The allocation coefficients for the remaining elements are taken from the values ​​in IAEA Report No. 19.

[0101] ② Concentration ratio

[0102] For elements Y and Fe for which EC recommendations do not provide default concentration ratio values, data from the IAEA .422 report are used; for Mo and Pr, the values ​​are temporarily set to 0. Concentration ratios for other elements corresponding to different aquatic organisms are provided by EC recommendations.

[0103] ③Internal and external irradiation dose rate conversion factor

[0104] The internal and external irradiation dose rate conversion factor is set to the default value recommended by EC.

[0105] ④ Residency Factor

[0106] The freshwater ecosystem uses the default residence factor value recommended by EC.

[0107] (2) Calculate the dose rate of the liquid effluent to the water frog.

[0108] According to the freshwater ecosystem dose rate calculation model (i.e., formula (3) of Example 1), the dose rate of each nuclide in the liquid effluent to the water frog was calculated to be 2.59E-02μGy / h. The nuclide that contributed the most was C-14, which had a dose rate of 2.57E-02μGy / h to the water frog.

[0109] Step 23: Compare the radiation dose rates of the marsh frog in terrestrial and freshwater ecosystems.

[0110] Based on the above calculations, for terrestrial ecosystems, the dose rate of the radioactive effluent from this nuclear facility to *Rhizophora stylosa* is 3.04E-03 μGy / h, with the largest contributing nuclide being C-14, which causes a dose rate of 2.15E-03 μGy / h. For freshwater ecosystems, the dose rate of the radioactive effluent from this nuclear facility to *Rhizophora stylosa* is 2.59E-02 μGy / h, with the largest contributing nuclide being C-14, which causes a dose rate of 2.57E-02 μGy / h. Therefore, the freshwater ecosystem with the larger calculated dose rate is used to evaluate the radiation impact of the radioactive effluent from this nuclear facility on *Rhizophora stylosa*.

[0111] The method for obtaining the radiation dose rate of amphibians in this embodiment ignores the distribution of residence factors in terrestrial and freshwater ecosystems, directly calculates the dose rate of amphibians in both ecosystems, and selects the result with the larger dose rate for evaluation. This allows for a rapid and conservative assessment of the radiation impact on amphibians. The method for obtaining the radiation dose rate of amphibians in this embodiment can be understood as a rapid calculation method.

[0116] Optionally, the device further includes a distribution module 33.
