INTERNET-OF-THINGS SENSOR FOR IONIZING RADIATION INSPECTION IN CONFINED SPACES

The purpose of this paper is to present an Internet-of-things sensor for ionizing radiation inspection of buildings and facilities for ionizing radiation sources and measuring the ionizing radiation dose. A design of a sensor applicable to indoor surveying is presented. The sensor is a lightweight module and is suitable for mobile use either installed on a remotely controlled or autonomous mobile unmanned platform. For test purposes a mobile ground based unmanned vehicle was developed by the authors and the sensor was mounted on that platform. In the case of the utilized testbed, the gamma/beta radiological sensor is directly connected to the main processor unit (digital signal processor microcontroller) of the unmanned platform. The latter was developed to prototype stage and is herein described. The presented novel design is compared to previous work while advantages over existing technology are established. Experimental results of measurements of radiation sources are shown and discussed.
