A nuclear radiation monitoring system with a transmission range of 10 km is developed and validated. The designed system can be used for remote monitoring of nuclear radiation and collecting the data at ground stations located far apart from active site. It can be used to interface any wireless nuclear radiation sensor and has 10 years of operating lifetime. The transceiver is implemented using novel Low Power Wide Area Network (LPWAN) technology which is specially designed for applications requiring long range transmissions at low data rate. The experimental testing of designed system shows that dose rate information can be transmitted upto 10 km in rural and 7 km in urban environment. Moreover, there is possibility of creating a network where number of different sensors located geographically apart can transmit to the same base station, thus providing simultaneous data analysis. © 2020 IEEE.
