In the village of Lia, Georgia, on December 2, 2001, Three lumberjacks discovered two 90Sr cores from Soviet radioisotope thermoelectric generators. These were of the Beta-M type, built in the 80s, with an activity of 1295 TBq each. The lumberjacks were scavenging the forest for firewood, when they came across two metal cylinders melting snow within a one meter radius laying in the road. They picked up these objects to use as personal heaters, sleeping with their backs to them. All lumberjacks sought medical attention individually, and were treated for radiation injuries. One patient, DN-1, was seriously injured and required multiple skin grafts. After 893 days in the hospital, he was declared dead after a fever caused by complications and infections of a radiation ulcer on the subject's back. The disposal team consisted of 25 men who were restricted to a maximum of 2 minutes worth of exposure (max. 20mSv) each while transferring the canisters to lead-lined drums.
