Estimation Method of γ-ray Irradiation Dose Based on Transcription Factor IIIA

Abstract

The embodiment of the invention discloses a [Gamma] ray irradiation dose estimation method based on a transcription factor IIIA, and relates to the nucleonic field. The irradiation dose is scaled through the changing of the transcription factor IIIA divalent zinc ion concentration. The [Gamma] ray irradiation dose estimation method based on the transcription factor IIIA employs the chemical colorimetry to detect the transcription factor IIIA divalent zinc ion concentration of different doses [Gamma] ray irradiation, and a dose-effect curve between the transcription factor IIIA divalent zinc ion concentration and the irradiation dose is established. According to the established dose-effect curve, a double blind method is employed to estimate the [Gamma] ray irradiation dose, the dose estimation range is wide and the operation is simple.

Description

technical field [0001] The present invention relates to nuclear science, in particular to a gamma ray irradiation dose estimation method based on transcription factor IIIA. Background technique [0002] With the wide application of nuclear technology in military and civilian fields, people pay more and more attention to radiation safety. The premise of radiation safety is accurate measurement of radiation dose. [0003] The dose of the radiation field cannot be measured directly, and the dose must be determined indirectly by using the changes of the measurable indicators caused by some ionizing radiation. At present, a variety of chemical dosimeters such as ferrous sulfate, cerium sulfate and potassium dichromate have been used in the field of radiation dose detection. Among them, the ferrous sulfate dosimeter is a chemical dosimeter configured with pure deionized water, sulfuric acid, ammonium ferrous sulfate and sodium chloride as raw materials. radiation dose.

AI Technical Summary

Problems solved by technology

[0004] The ferrous sulfate dosimeter is a classic chemical dosimeter, which can accurately calibrate the radiation field dose, but the ferrous sulfate chemical dosimeter also has certain defects, only 0.04-0.4kGy (X / γ-ray), that is, the ferrous sulfate dosimeter The dose scale range is relatively narrow, which greatly limits the application range of the ferrous sulfate dosimeter, especially in the radiation environment outside the scale range, it is difficult to use the ferrous sulfate dosimeter to measure the dose, resulting in 0.04-0.4kGy There is a lack of simple and effective measurement methods outside the measurement range, and can only be measured by some cumbersome means
