So I'm summarizing:
In 1980, a building is finished being built in Kramatorsk, Ukraine. The following year, an 18-year-old woman living in apartment #85 dies suddenly. Two years later, it is her 16-year-old brother who dies. Then the mother. Despite these serial deaths - all of them from leukemia - the residents are not more worried than that. Doctors think it's "bad heredity."
A new family moves in. This time, it's the son who dies of lightning leukemia. The father decides to investigate.
The result of the investigation (hold on to your hat):
In 1970, a highly radioactive cesium capsule that was part of a radiation counter is misplaced in Karansky's quarry. The fruitless search is abandoned after a week. The stones extracted from the quarry are used for the construction of the building 7 Mariyi Pryimachenk street. The radioactive capsule is found in the wall separating the #85 and #52 appartments, right next to the children's bed.
Four dead, seventeen irradiated.
Why am I talking about this? Because a radioactive capsule was just lost on a road somewhere in Australia. If you happen to be driving by...
