"During a search our special services found a small container which probably contains earth from Chernobyl, the radiation dosimeter readings were off the charts. Plutonium was also detected.

The account of the raid was issued two weeks after it occurred. Authorities are receiving assistance from radioactive material management personnel from MosNPO Radon.
