Portable personal dose monitoring system and device based on sharing mode

Abstract

The invention discloses a portable personal dose monitoring system and device based on a sharing mode. The system adopts a semi-insertion storage mode of an EPD (Electronic Personal Dosimeter), achieves the high systematization and integration, achieves the automatic receiving and transmitting and data management of the EPD on the basis of the sharing mode, is both portable and expandable, and canmeet monitoring requirements of temporary monitoring occasions. Due to the use of the system, the use management of the EPD can be optimized, the operation process of a user is simplified, the automatic reading of monitoring data is realized, the error probability of the monitoring process can be reduced, and the monitoring efficiency and the equipment utilization rate are increased. According tothe portable personal dose monitoring system and device based on the sharing mode, based on the sharing mode, the utilization rate of the monitoring system is increased, portability and expandabilityare achieved at the same time, and the personal monitoring requirement for external irradiation on the temporary special monitoring occasions is met.

Description

technical field [0001] The present invention relates to the technical field of radiation protection, in particular to a portable personal dose monitoring system and device based on a shared mode. Background technique [0002] The EPD (Direct Reading Personal Dosimeter) is a small device for personal monitoring of external exposure by radiation workers. Due to its advantages of instant readability of monitoring results and alarm function, it has been widely used in personal monitoring of external exposure in radioactive work, especially in special workplaces with high radiation levels. [0003] The national health standard "Specifications for Personal Monitoring of Occupational External Exposure" (GBZ128-2019) requires that when the expected external exposure dose may exceed the dose limit, staff should wear an alarm in addition to a personal dosimeter for routine monitoring. type personal dosimeter or accident dosimeter. Many units have or are gradually beginning to requir...

Problems solved by technology

[0004] The complex form of personal dose monitoring system with comprehensive functions has been able to better meet the needs of automatic personal dose monitoring in large nuclear facilities, but at present, the large fixed equipment of this type of monitoring system, its EPD transceiver device and data reading device They are all large in shape, and are only suitable for fixed installation at the entrance and exit of the control area, and cannot meet the monitoring needs of temporary special monitoring occasions that still mainly use EPD for supplementary monitoring.

Most of the relatively simple personal dose monitoring systems are only composed of EPD, data reading device and computer system (some systems even only have EPD). The intermediate process (switching on and off, parameter setting, etc.) even requires manual recording of monitoring data, which has a high probability of error, and there is no identification device, and there is no automatic personnel authorization management function, which is not convenient for on-site radiation protection management
