PurposeResearch
Objectives1. To carry out a major radiological survey of the Irish Sea.
2. Further trials of gamma spectrometric equipment to monitor in situ the seabed and seawater in the Windscale and Clyde areas.
3. To carry out a radiological survey of the Clyde area.
4. To carry out trials between Van Veen Grab, Craib corer and in situ gamma spectrometry of the seabed, in conjunction with the MOD Naval Radiological Protection Service.
5. Collection of seabed samples off the west coast of Scotland for determination of background levels of radiation.
6. Collection of seawater samples at stations in the North Sea and English Channel, for the determination of weapon test fallout levels in seawater.
7. To fish off Windscale for up to 100 of the marked plaice released during Clione 4b/1967.

North Sea water samples in the Firth of Forth area were taken en route. Background grab sampling and in situ gamma probe measurements were completed in Loch Ewe. Measurements of the shielding effects of increasing depths of seawater on the gamma probe's response to cosmic radiation were made whilst anchored overnight in deep water (42 fathoms, Loch Goil). Water samples were collected in the English Channel and Southern North Sea.
