results show that:
- levels are still high
- concentrations of iodine-131 are higher than for caesium-137
- levels are higher at water surface than bottom. This is a little anomalous in that highrest concentrations in fish come from bottom-dwelling fish (launce) but they may have been caught near shore.
- the concentrations are more heterogenous than before. Mpost sensors do not detect any activity
- the levels of Cs-137 are such that they could cause contamination of fish above the limit. We used the "worst case" ratio - 1 Bq/litre in water results in 100 Bq/kg in wet fish. The conversion factor comes froma press release from Japanse Fisheries Agency
