Thermoluminescence card dosimeter

Abstract

The present invention relates to an electric heating thermoluminescence card dosimeter used for monitoring the radiation dose in the nuclear radiation dose monitoring field. The thermoluminescence card dosimeter comprises an upper casing, a bottom casing, a tray, a pressure sleeve, a positioning plate and a coating film, the tray is embedded between the positioning plate and the pressure sleeve, adetector is placed on the tray and is covered by the coating film, and the upper casing and the bottom casing are connected via rivets. The thermoluminescence card dosimeter is smooth in overall surface, beautiful in appearance, light in weight, small in size and compact in structure and good in function, is dustproof, water proof, safe and reliable, is not easy to damage and simple and convenient to turn on, can realize a superficial dose Hp (0.07), depth dose Hp (10), eye body dose Hp (3) and energy discrimination multi-parameter measurement function, and is suitable for measuring the personal conventinal dose and the accident dose of the X, gamma and beta rays.

Description

technical field [0001] The invention relates to a thermoluminescence card dosimeter in thermoluminescence detection technology, and belongs to the technical field of radiation dose measurement. Background technique [0002] Thermoluminescence detector is a solid-state dosimeter with good energy response, high sensitivity, wide dose response range, high measurement accuracy, light weight, small size and small environmental influence factors, and can measure X, γ, β and medium It is widely used in personal and environmental dose monitoring and other fields. [0003] The thermoluminescent dosimeter can be configured with LiF: Mg, Cu, P or LiF: Mg, Ti thermoluminescent detector (referred to as detector), which is used for monitoring the deep dose, superficial dose and eye lens dose of radioactive workers. Its performance should meet the requirements stipulated in the national standard "Thermoluminescent Dosimetry System for Personal and Environmental Monitoring" (GB10264-88). ...

AI Technical Summary

Problems solved by technology

[0004] At present, two kinds of heating methods are adopted in foreign thermoluminescence automatic measuring devices, namely hot air heating (Harshaw Company of the United States) and infrared heating (Panasonic Company of Japan), while the present application proposes an electric heating method. The output devices are all measured by electric heating, and there are problems such as single measurement parameters, complicated operation, slow speed, and inconvenient management.

This application adopts the method of indirect electric heating (refer to "An Electric Heating Card Thermoluminescent Measuring Heating Device", utility model patent application number: 201310051395.3), which solves the problem of the existing technology well under the condition of satisfying multi-parameter measurement.
