NEW TECHNOLOGY FOR CONDUCTING RADIATION HAZARD ASSESSMENTS: THE APPLICATION OF THE UNDERWATER RADIATION SPECTRAL IDENTIFICATION SYSTEM (URSIS) AT THE MASSACHUETTS BAY INDUSTRIAL WASTE (U.S.A.)

摘要

The Underwater Raidation Spectral Identification System (URSIS) is a portalbe spectrometer used for the in situ detection of radioactivity in the marine environment. This paper reports on the first time application of this technology to assess, in a preliminary manner, the potential radiation threat to the public and environment at an aquatic disposal site - the Massachusetts Bay Industrial Waste Site (IWS). Utilizing the meneuvering capabilities of ROV and manned submersible vehicles, the URSIS was successfully positioned close (5-10 cm) to waste containers for a period sufficient to detect, in real time, the presence of radioactive materials.
