Description

Technical Field

[0001] The present application relates to the field of radiation measurement technology, and in particular to a method, device, electronic device and storage medium for rapid detection of fish radioactivity based on the bremsstrahlung effect. Background Art

[0002] Environment 90 There are three main sources of Sr: fallout from nuclear explosions, releases from nuclear accidents, and emissions from the operation of nuclear facilities. 90 Sr is one of the key monitoring objects in radiation environment detection. 90 Sr is a pure β-radionuclide and a bone-loving radionuclide, which is easily enriched in fish bones. 90 The half-life of Sr is 28.8 years. After being transferred to the top of the food chain through food and absorbed by the human body, this type of nuclide is easily absorbed by the human body and accumulates in the bones, which may cause cancer. Humans still lack effective disposal technology for artificial radioactive pollutants entering the ocean. They can only strengthen monitoring and reduce the consumption of fish and other aquatic products.

[0003] Existing fish radioactivity detection methods:

[0004] 1) Direct radiation measurement method: Use radiation measuring instruments such as a Gate counter to perform direct in vitro measurements on fish specimens to detect whether the fish have abnormal radiation conditions.

[0005] 2) Liquid scintillation method: Take fish samples and water samples, extract body fluids, add liquid scintillation reagent, and place them in a liquid scintillation counter to measure to detect whether there are radionuclides in the samples.

[0006] 3) Radiochemical analysis: Use a high-purity germanium gamma detector to perform radiochemical analysis on fish samples to quantitatively detect the content of radionuclides in the samples.

[0007] 4) Micronucleus test in biological samples: extract fish blood products and observe the changes in micronuclei to reflect whether the fish are affected.

[0008] Analyzing the above existing technologies, the following problems exist:

[0009] 1) Direct radiation detection can only detect radioactive substances on the surface of fish, such as α, β, and γ rays;

[0010] 2) The accurate measurement of liquid scintillation method requires the fish sample to be placed in a specific instrument for a long time;

[0011] 3) Radiochemical analysis has many steps, is time-consuming, and large doses of reagents pose a safety hazard to laboratory personnel, and waste liquid is difficult to handle;

[0012] 4) The micronucleus test in biological samples also has a long analysis time and cannot meet the needs of rapid emergency monitoring. Summary of the invention

[0057] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0058] A method and device for rapid detection of fish radioactivity based on the bremsstrahlung effect according to an embodiment of the present application will be described below with reference to the accompanying drawings.

[0059] Figure 1 A schematic diagram of a method for rapid detection of fish radioactivity based on the bremsstrahlung effect provided in an embodiment of the present application. The method comprises the following steps:

[0060] Step 101, obtaining a fish sample, and making the fish sample into a biological measurement liquid sample.

[0061] The method of the present invention is mainly used for detecting the content of radioactive elements in fish. Before marine fish enter the domestic food market, it is usually necessary to detect the content of radioactive elements in their bodies, provide a general action level for marine fish foods that exceed the standard, mark the type, source and other information of the marine fish foods that exceed the standard, and update the database of fish and aquatic products to prevent the subsequent introduction of similar marine fish.

[0062] In an embodiment of the present invention, a scenario is set to test a batch of marine fish food to be introduced into the domestic fish food market.

[0063] In an embodiment of the present invention, the biometric liquid sample is prepared according to the following steps:

[0064] Select at least one of the fish species to be tested as a fish sample;

[0065] Specifically, if a batch of marine fish food to be entered into the domestic fish food market is of the same type of fish, one or several fish with the average weight of all the fish are selected as fish samples; if there are at least two types, at least one fish of each type is selected as a fish sample.

[0066] Each fish sample was de-fleshed and bones were retained to form a biometric sample;

[0067] A nitric acid (3 mol / L)-oxalic acid solution (0.05 mol / L) was added to the biological measurement sample, and the solution was diluted with water to a fixed volume to prepare a biological measurement liquid sample.

[0068] Specifically, nitric acid (3 mol / L)-oxalic acid solution (0.05 mol / L) was added, 191 mL of concentrated nitric acid and 6.3 g of oxalic acid dihydrate were dissolved in 800 mL of water, and finally diluted with water to 1 L as a biological measurement liquid sample.

[0069] Step S102: Based on the Bremsstrahlung effect, the content of radioactive elements in the biological measurement liquid sample is measured.

[0070] When the present invention determines the content of radioactive elements in a biological measurement liquid sample, the content of radioactive elements is 90 Sr element content. Considering the radioactive substances in water such as 131 I. 137 Cs is easily transported and deposited in animal meat. 90 Sr is easily deposited in bones, so the present invention measures the 90 Sr was used to estimate the radioactive dose value in the fish in the area.

[0071] In an embodiment of the present invention, determining the content of radioactive elements in a biological measurement liquid sample specifically includes the following steps:

[0072] Through the bremsstrahlung effect, 90 Sr daughter 90 The 2.28MeV high-energy β emitted by Y interacts with matter to produce photons;

[0073] The photons are detected by a high-purity germanium crystal detector, and the detection results are subjected to spectrum analysis;

[0074] Determination of radioactive elements in bioassay liquid samples based on spectrum analysis results 90 Sr content.

[0075] Bremsstrahlung is the radiation produced when high-speed electrons suddenly slow down. It generally refers to the radiation emitted by charged particles during collisions (especially Coulomb scattering between them). For example, this radiation is produced when a high-energy electron collides with an atomic nucleus.

[0076] In the present invention, 90 Sr daughter 90 When the 2.28MeV high-energy β electrons emitted by Y interact with matter, the bremsstrahlung effect is generated. Measuring the photons of fixed energy level produced by bremsstrahlung can avoid the problem of low efficiency of direct B-ray measurement. Bremsstrahlung has similar properties to γ-rays and has relatively strong penetrating power. High-purity germanium detectors can be used to directly measure liquid samples.

[0077] During spectrum analysis, the container containing the biological measurement liquid sample is placed in the high-purity germanium crystal detector; the detection time is set and the high-purity germanium crystal detector is turned on; the electrical signal of the detection result generated by the high-purity germanium crystal detector is pre-amplified after passing through a resistor network, and the pre-amplified electrical signal is input into the pulse shape analysis system for spectrum analysis.

[0078] Step S103: Compare the radioactive element content in the biometric liquid sample with a preset warning value, and issue a warning based on the comparison result.

[0079] b. GB14882-1994 "Limited Concentration Standards for Radioactive Substances in Food" stipulates the export limit concentrations of 12 types of radioactive substances in major foods. This standard is based on the annual effective dose to the public from dietary intake not exceeding 5mSv, as shown in the following table:

[0080] variety <![CDATA[ 90 Sr]]> Meat, fish and shrimp <![CDATA[2.9×10 2 ]]>

[0081] Table 1 Limit concentration of artificial radionuclides specified in GB14882-1994 (Bq / kg)

[0082] Based on the above standards, preset warning values ​​are set.

[0083] Specifically, when setting the preset warning value, the following steps are included:

[0084] The radioactive element 90 The intake limit of Sr is used as the set value for data warning to calculate the consumption weight limit;

[0085] Based on the sample weight of the fish sample, the edible weight limit corresponding to the fish sample weight is calculated as the preset warning value.

[0086] After the detection is completed, the method also includes the step of dynamically updating and forming a database for the consumption of fish and aquatic products.

[0087] Furthermore, in order to implement the method for rapid detection of fish radioactivity based on the bremsstrahlung effect provided by the present invention, the following is designed: Figure 2 The rapid monitoring and early warning device shown includes a high-purity germanium crystal detector a, a fishbone stirring knife b, a beaker c, an acid injection port d, an acid discharge port e, a rotary drive device f, a pulse shape analysis system g and a radiation dose early warning system h.

[0088] like Figure 2 The fish bone stirring blade b is extended into the beaker c to crush the fish bones placed in the beaker c, and the rotating driving device f is connected to the fish bone stirring blade b to drive the fish bone stirring blade b. The required acid liquid is injected into the beaker c through the acid injection port d, and the acid liquid is discharged through the acid discharge port e after reacting with the fish bones in the beaker c.

[0089] The detection result of the high-purity germanium crystal detector a is transmitted to the pulse shape analysis system g for spectrum analysis, and then the analysis result is transmitted to the radiation dose warning system h for early warning.
