A METHOD FOR THE LOCATION OF RADIOACTIVE SOURCES IN MOTION

There is an increasing need for the ability to detect radioactive material. Many approaches have been developed to deal with stationary or semi-stationary sources. Lately interest has been expressed in the ability to detect and locate moving sources at speeds relevant to pedestrians and slow moving traffic. This presentation describes a measurement conducted with an array of low-cost plastic scintillator detectors to detect radioactive sources moved with speed not exceeding 25 km/h. The measurement shows a proof-of-principal for a cost-effective approach under realistic conditions.
