Radiation dose monitoring system

摘要

The present invention can measure and transmit an accurate radiation dose in a stable state of charge by using an independent power source capable of self-generation even where the power supply of nuclear facilities is restricted, regardless of external environment and stimuli, and can be stably monitored from the outside. It's about the technology that makes it possible. The electric power generated from the beta battery module installed in the radiation space according to the present invention to generate electric power using energy generated by radioactive materials is charged to the secondary battery, and using this charging electric power, radiation is emitted at a preset radiation measurement cycle. At least one transmitter that acquires a radiation measurement value through a detection sensor, converts radiation information including the radiation measurement value into a wireless signal and transmits it to an external receiver, and radiation received from the transmitter at a preset radiation measurement cycle A receiving device that receives information and transmits it to a monitoring terminal, and a monitoring terminal of a dual structure that expresses and outputs the radiation information received from the receiving device on a radiation area map in which the transmitting devices are installed, wherein the transmitting device is configured with a preset When the amount of charge charged in the secondary battery for the radiation measurement time is less than the reference charge amount, the current radiation measurement period is changed longer, and a pulse pattern having the number of pulses corresponding to the changed radiation measurement period per unit time is generated and wirelessly transmitted, If radiation information is not received in the current radiation measurement period, the receiver counts the number of pulse signals received for a unit time from the radio signal received from the transmitter thereafter, and sets the currently set radiation measurement period to a new radiation measurement corresponding to the number of pulse signals. It is characterized in that it is set to change periodically.
