Gamma survey probe for use on ocean, lake, estuary and river sediments |
摘要 |
An underwater gamma radiation survey probe adapted to be towed by a tow cable along the bottom of a body of water. The probe comprises a tubular shell with a nose cone having a waterproof connector for the tow cable. The nose cone closes one end of the tubular shell in a waterproof manner and an end plug closes the other end of the tubular shell in a waterproof manner. At least one weight of high density material is located in a lower half of the shell with that weight containing a cavity having an opening which faces the tubular shell. The weight maintains the orientation of the probe such that the opening faces downwards and a radiation detector in the cavity can detect radiation from the bottom surface.
