Event Location:	Poland, Poznan	INES Rating:	1 (Final)

On the 6th of March 2015 total of 22 containers with Co-60 category 5 (activity between 40 MBq and 200 MBq on 2015-03-06) radioactive sources were reported stolen from a storehouse in Poznan. On the 10th of April the licensee informed that 7 of the containers previously reported stolen have remained intact inside the storehouse. Aggregated activity of the stolen sources equals about 1,7 GBq.
Between the 8th and the 10th of April 8 of the stolen sources were discovered by the police in Poznan. Individuals who stole the sources have dismantled shielding containers in order to sell those for scrap. Some of the sources were damaged and caused spot contamination (inside a workshop building and some soil outside, no contamination of people was detected). The 8 radioactive sources, which were found in Poznan, have been secured. Contaminated soil has been also removed. Decontamination of the workshop building was completed. No contamination of people nor deterministic effects were detected. Biological retrospective dosimetry proved that there were no significant overexposures.
Location of 7 stolen sources remains unknown.
INES Rating: 1 - Anomaly (Final) as per 11 April 2015
Il y a donc 7 sources de CO 60 dans la nature. 
Heureusement a ce jour il n'y aurait pas eu d'impact humain, même si certains individus ont ouvert les canister scéllés. (faut pas etre malin...)
