Following the deployment of the TORONE platform at the JSI TRIGA Mk II nuclear reactor, one of the tasks undertaken was dose mapping in the reactor hall whilst operating. The robot was equipped with gamma radiation detection, and whilst being driven around was capable of recording count rate (counts per second - cps). These individual points can then be interpolated into a map of the entire environment.
As highlighted in the paper published in Nature Scientific Reports, from hotspots identified in the map it was possible to infer radiation sources from other robot sensors such as camera images. The map is generated by the robot as part of its navigation and localisation, and is a convenient way to represent spatially resolved data.
