| Purpose | Research |
| Objectives | I. To re-examine the concentration contours of Caesium-137 and Caesium-134 in seawater of the Irish Sea following increased rates of discharge from B.N.F.L., Windscale, Cumberland.
2. To collect samples of seabed from selected stations in the Irish Sea for the examination of the distribution of radioactivity with depth from the surface layer in both the solid and liquid phases. 3. To record the total gamma count rate from seawater of the Irish Sea. 4. To collect seawater samples for the measurement of the weight of the suspended load at selected stations in the Irish Sea. 5. To collect seawater samples in British Isles coastal waters for radiocaesium and tritium analyses. 6. To collect fish samples in the western Irish Sea for radiocaesium analyses. |
