PurposeResearch
Objectives1. To continue the examination of the distribution of Strontiurn-90, Caesium-134, Caesium-137, Plutonium-238, Plutonium 239/24O and Americium-243 in British Isles coastal waters.
2. To continue work on determination of the oxidation states of
plutonium in seawater,
3. To determine the suspended load in seawater at stations where
seawater samples are to be analysed for plutonium.
4. To record the gamma count rate, in a selected energy range, from
surface seawater of the Irish Sea and its immediate approaches.
5. To measure the concentrations of Polonium-210 in seawater and in
plankton.
6. To collect 5 core samples of the seabed of the north Irish Sea using
the Reineck box corer on mud and the Tennant box corer on sand.
7. To measure surface and bottom seawater temperatures at selected stations in the Irish Sea for Nr R J Wood.
