AN UNDERWATER SURVEY SYSTEM FOR RADIONUCLIDE-TAGGED SEDIMENT TRACING

H.R. Brashear, F.N. Case

Abstract


Survey equipment for use in tracing sediment tagged with radionuclides has been designed and field tested The system is unique in its ability to operate on the dry beach, m the surf, and in deep water, making it possible to synoptically examine the beach face, surf zone, and off-shore marine environment The ball-shaped radiation detector vehicle is towed behind an amphibious vessel Data are collected on punched tape at a rate of one set of data (position, radiation counts, time) every two seconds Gold-198 and xenon-133 have been used for tagging sand indigenous to the survey area under study Operational characteristics and detection sensitivity are discussed.
