Abstract: Objective A remote multi-part personal radiation dose detection system is designed with ATmega32A single chip microcomputer as the control core. Methods First of all, the geiger counter tube module collects the radiation signal of the surrouding environment. Secondly, using ATmega32A Microprocessor of Slave computer to calculate the collected signal. Finally, it is sent to the host receiving device or mobile APP through Bluetooth module,so as to realize real-time detection of radiation data, remote transmission and security alarm. Results The system is measured in the same environment as the RG1100 radiometer, with a maximum difference of 0.03 μSv/h.This shows that it can stably realize the functions of radiation measurement, monitoring, alarm, remote connection and multimodal display. Conclusion The system has the advantages of good portability (easy to carry), low power consumption, accurate measurement and so on. It has certain reference value and practicability.
