UNDERWATER RADIATION DETECTION USING A PRINCETON GAMMA TECH INSTRUMENTS SCINTILLATION DETECTOR ON AN IROBOT SEAGLIDER AUV

On March 11, 2011, an earthquake and resulting tsunami did extensive damage to the Fukushima Daiichi nuclear power plant in Japan. Within days of the disaster, officials began monitoring the oceans and seafloor extending out from the disaster site. Efforts have consisted of collecting samples from varying depths in the water column as well as sediment samples from the seafloor at predetermined test sites. These samplings have been limited in their point nature and by the 30km radius keep out zone that was established. In response to the need for persistent monitoring, iRobot has collaborated with Princeton Gamma Tech Instruments (PGT) to develop an underwater scintillation detector that can be installed on the Seaglider AUV. The detector is a 3x3 NaI crystal with integral PMT and HV supply and is capable of storing 1,000 spectra with all associated data. The sensor is packaged in a watertight housing and the Seaglider can be programmed to loiter in a specified area to provide a spectroscopic survey. Data from tank and ocean testing conducted by iRobot and PGT will be presented.
