The thieves, attracted by the apparently simple prospect of looting some non-ferrous metals, stole around 500 kilograms of stainless steel, aluminium and lead. As for the radioactive power element, they threw it out into the frozen sea some 200 meters away from the lighthouse. The "hot" strontium capsule melted the ice and went down to the sea floor. But even though the ice covering the spot where the RHS sank was one meter thick, the gamma radiation exposure dose rate directly above the sunken unit reached over 0,3 Sv/h40.
