Method and system for monitoring radiation dose in room where nuclear power plant personnel work in real time

Abstract

The invention relates to a radiation dose real-time monitoring method and system for a room where nuclear power plant personnel work, and the method comprises the steps: enabling a portable dosimeter to obtain the real-time radiation information and real-time position information of a worker after the worker enters a control region of a nuclear power plant; the portable dosimeter sends the real-time radiation information and the real-time position information to a background server; the background server receives the real-time radiation information and the real-time position information and triggers a calculation task; and after triggering the calculation task, the background server calculates the radiation data of the worker in the current room according to the real-time radiation information and the real-time position information. According to the invention, the radiation condition of the staff can be refined to the room level, more accurate and more comprehensive dose information is provided for radiation protection management, the analysis of room radiation risk is facilitated, more powerful data support is provided for the formulation of protection measures, and the safety of the staff is improved.

Description

technical field [0001] The invention relates to the technical field of nuclear power plant radiation monitoring, in particular to a method and system for real-time monitoring of radiation dose in a room where nuclear power plant personnel work. Background technique [0002] At present, radiation workers in nuclear power plants work in the control area of ​​the nuclear power plant and wear personal portable dosimeters to record radiation doses during work. Dose value results. With the application of wireless communication technology in some nuclear power plants, combined with portable dosimeters with wireless communication capabilities, managers can obtain real-time dose values ​​of dosimeters worn by staff. However, although this method solves the real-time problem of data acquisition, the real-time data obtained by this method can only reflect the cumulative dose produced by the staff from entering the control area to the current moment, and cannot accurately reflect the t...

AI Technical Summary

Problems solved by technology

However, although this method solves the real-time problem of data acquisition, the real-time data obtained by this method can only reflect the cumulative dose produced by the staff from entering the control area to the current moment, and cannot accurately reflect the time when the staff worked at a certain time. The dose generated in the room makes it impossible to accurately trace and track the specific radiation situation
