Mentoring method and device for measuring effective dose on real time

Abstract

The invention belongs to the radiation dose monitoring technology, and specifically relates to a monitoring method and device for measuring effective dose on real time. The method comprises the steps of manufacturing a simulated human organ or tissue model; performing monte carlo simulation calculation through a computer to obtain absorbing dose of a plurality of points in the organ or tissue model so as to obtain an average value; finding out the points in which the absorbing dose is the same as the calculated average value in the organ or tissue model; arranging a detector on the points corresponding to the organ or tissue model, wherein the measurement result represents the average absorbing dose DT, R of the organ or tissue; calculating the effective dose for a human body by the calculation formula of the effective dose E according to the weight factor wT of the organ or tissue and the selected value of the radiation weight factor wR. With the adoption of the method and the device, the effective dose for workers can be directly measured, and thus the radiation protection can be conveniently optimized.

Description

technical field [0001] The invention belongs to radiation dose monitoring technology, in particular to a monitoring method and device for real-time effective dose measurement. Background technique [0002] With the increase of nuclear power plants in my country and the wide application of nuclear technology, the number of workers receiving ionizing radiation is increasing year by year, and people pay more and more attention to radiation protection. In the practice of radiation protection, one of the main purposes of measurement and calculation is to quantitatively explain the actual or possible radiation exposure of individuals, so it is necessary to involve the radiation dose related to the exposed individuals, and then calculate the radiation damage to humans. Hazard size. [0003] The three principles of radiation protection are protection legitimacy, optimization, and dose limit. The amount used in the relevant national standards when specifying the dose limit is the ef...

AI Technical Summary

Problems solved by technology

[0006] The average absorbed dose D in a human tissue or organ T T,R It is difficult to measure. At present, there is no real-time measurement technology for effective dose. In order to implement radiation protection dose limit management, practical quantities (such as Hp(10) equivalent) are generally used to estimate

According to relevant ICRP publications and domestic and foreign studies, in some radiation sites, the gap between the two is relatively large, which brings great troubles to the effective implementation of personal dose limits and the optimization of radiation protection.
