Background

National laws and regulations require that personnel who engage in or are involved in radiation must receive personal dose monitoring and build a personal dose profile. GBZ 128-2016 personal Specification for occupational irradiation personal monitoring specifies the type, category and monitoring requirements of personal dose monitoring, and particularly describes the personal dose monitoring process from the aspects of personal dose monitoring method, personal dose meter wearing and calibration, dose evaluation, etc. The purpose of personal dose monitoring is to evaluate the effective dose of a radiation worker and the equivalent dose of a main irradiated organ, provide the change trend of radiation dose of the worker and a workplace and the sufficiency information of the protection condition of the relevant workplace, and provide data for the optimization of radiation protection; the personal dose monitoring data is used for evaluating abnormal irradiation and accident irradiation dose conditions, and also provides useful data for radiation epidemiological research. Therefore, it is very important to perform personal dose monitoring work and ensure the health of workers and the safety of working environment.

In recent years, related departments perform national personal dose monitoring capability assessment work every year, and require technical service organizations developing personal dose monitoring to participate in personal dose comparison work. The comparison work firstly needs to distinguish the type and energy of the emergent ray and then determines the dose value. Thus, there is a need for a discriminatory dosimeter.

The personal dosimeter used in the market at present comprises a personal dose box and a detection element, both adopt a semi-sealed structure, and have a dustproof function. The dosimeter is worn by adopting an elevator structure, and the numbering position is adhered by adopting a printed plastic bar code or a blank label, so that personnel of different work types can be distinguished conveniently. After the personal dose laboratory retrieves the personal dose, the dose box needs to be disassembled in the laboratory, and then the detector inside is taken out to measure. Generally, place the dosage meter in the desk edge, insert the bottom of dosage meter with opener, pry the bayonet downwards and open the dosage meter. The two sides of the dosimeter can be held by hands, the bottom end of the dosimeter is inserted into the opening tool, the bayonet is pried downwards to open the dosimeter, but the dosimeter is required to face upwards when the detector is arranged, so that the detector is prevented from falling out when the detector is opened. After the dose detector is replaced regularly, the detector is placed in a slot of the dosimeter according to the requirement; and (4) covering the upper cover of the dosimeter, pressing the bottom of the upper cover of the dosimeter by a thumb and placing the forefinger below the base of the dosimeter, and forcibly squeezing the bayonet of the dosimeter to close the dosimeter.
