Iodine-131 release in the environment |
The waste division of the Institute for radioelements (IRE) has performed a transfer of liquid radioactive waste from one tank to another one. Immediately afterwards – for reasons still unknown – radioactivity was released through the stack. The release is related to the vapour phase above a liquid waste solution in a tank.
The quantity of radioactivity released into the environment is estimated at 45 GBq I-131, which corresponds to a dose of 160 microsievert (effective dose) for a hypothetical person remaining permanently at the site’s enclosure.
Note that the actual rating is based on the INES 2001-Manual and its corresponding addenda
This incident did not cause a contamination of the personnel, and their dose limits were neither exceeded.
The FANC requested the shutdown of the production till the solution of the problem.
