Human body radiation tissue equivalent material and dose measurement model

Abstract

The invention relates to a human body radiation tissue equivalent material and a dose measurement model. The human body radiation tissue equivalent material is determined based on the energy loss rateof a material composed of ICRU element proportion recommendation values, wherein the difference between the ionizing radiation energy loss rate of the composed material and the ionizing radiation energy loss rate of the human body radiation tissue equivalent material is less than 5%. The dose measurement model comprises a radiation dose measurement ball model or a radiation dose measurement flatplate model; materials of the model are all the human body radiation tissue equivalent materials, a measuring groove used for containing a radiation detector is formed in the model, and the radiationdetector is used for measuring the radiation dose of a to-be-measured position under the set radiation condition. According to the invention, the reasonable human body radiation tissue equivalent material and the dose measurement model are provided for monitoring the dose of human organs.

Description

technical field [0001] The invention relates to the technical field of human tissue equivalent materials and dose measurement, in particular to a human body radiation tissue equivalent material and a dose measurement model. Background technique [0002] The development of modern nuclear technology, the test of new strategic weapons and equipment, the expansion of the sea, air and space environment of strategic territory, especially in manned spaceflight, aviation polar flight, nuclear submarine and land-based nuclear weapon test, nuclear power plant safety, large accelerator experiment, radiation therapy, proton In terms of medical treatment and heavy ion therapy, the types of ionizing radiation (including high-energy particle radiation) are becoming more and more diverse, and the issue of radiation human safety has also received increasing attention. In order to protect the health of personnel and the normal operation of weapons and equipment in the environment of ionizing ...

AI Technical Summary

Problems solved by technology

In order to protect the health of personnel and the normal operation of weapons and equipment in the environment of ionizing radiation, dose monitoring is the core measurement index. The ICRP No. 103 report of the International Commission on Ionizing Radiation Protection and my country's national standard GB 18871-2002 "Ionizing Radiation Protection and Radiation Source Safety The Basic Standard requires that the effective dose based on human organ monitoring be used as an evaluation index, and as the basic support system for human organ dose monitoring, that is, the human organ dose measurement standards, methods, and specifications for ionizing radiation have not yet been established in my country and need to be developed urgently. research in this field
