Description

Method for providing an optimal route to a worker based on radiation dose and an electronic device using the same The embodiments of the present disclosure relate to a method for calculating radiation exposure levels within a nuclear reactor facility (specifically, nuclear facilities and radiation-related facilities) and providing any radiation worker (hereinafter referred to as "worker") with information on a work environment that minimizes radiation exposure and an optimal movement path, and an electronic device utilizing the same. More specifically, the invention relates to a simulation system for radiation work and evacuation training during normal operation, planned preventive maintenance (Overhaul), and accidents in a nuclear reactor facility. In order to prevent and respond to potential radiation exposure at nuclear reactor facilities, it is necessary to thoroughly analyze all possible scenarios for various radiation operations during normal operation and planned preventive maintenance, as well as in the event of an accident. In particular, it may be important to establish a simulation training system that minimizes the spread of radioactive materials and supports a rapid response in the event of an accident. It may be necessary to establish an integrated radiation dose prediction and diagnosis system and a realistic immersive work training system to support worker positioning and relocation, adjustment of detailed work processes, and rapid evacuation in order to minimize worker exposure during normal operation, planned preventive maintenance, and accidents at nuclear reactor facilities.
