60 mill Bq released to air, over 200 mill Bq leak to sea each hour

On December 16 it was reported  that

Levels of radioactive materials released outside the plant have declined to 60 million becquerels per hour, one-13 millionth of the levels at the time when the accident occurred. Additional radiation levels at the plant borders have fallen to a maximum of 0.1 millisievert per year, below the government target of 1 millisievert.

Currently, the water in the harbour has a radioactive density averaging at least 150 Bq/L, and every day about 35,000 tons of water enter and leave the port on the tides, carrying about 5 GigaBq of Cs137 and Cs134 with it…. see the data here
