GreenPeace comes through - independent sea radiation measurements 5/25

"The new data shows that some seaweed contamination levels are not only 50 times higher than safety limits – far higher than our initial measurements showed – but also that the contamination is spreading over a wide area, and accumulating in sea life, rather than simply dispersing like the Japanese authorities originally claimed would happen.

"Other samples showed lower than expected concentrations of caesium, but much higher levels of iodine than expected, which raises serious concerns that contaminated water is continually leaking from the nuclear plant.
