[ RadSafe ] Radioactive medicine being tracked through rivers

[Olsson Mattias :MSO]

Just as a reference, a normal value for an annual release of I-131 at
the Forsmark NPP where I'm employed is about 2 MBq per unit (BWR). One
unit has had trouble with several fuel failures and went up to 500 MBq
released during 2011.

To be compared to I-131 in medical treatments, if interested.
