The Kramatorsk radiological accident was a radiation accident that happened in Kramatorsk, Ukrainian SSR from 1980 to 1989. In 1989, a small capsule containing highly radioactive caesium-137 was found inside the concrete wall of an apartment building, with a surface gamma radiation exposure dose rate of 1800 R/year.[1]

Caesium-137 source

The source, originally a part of a radiation level gauge, was lost in the Karansky quarry. The gravel from the quarry was used in construction.[2] The cesium capsule ended up in the concrete panel of Apartment 85 of Building 7 on Gvardeytsiv Kantemirovtsiv Street, between apartments 85 and 52.[1]

Over 9 years, two families lived in Apartment 85.[1] A child's bed was located directly next to the wall containing the capsule.[1] By the time the capsule was discovered, 4 residents of the building had died from leukemia[1] and 17 more had received varying doses of radiation.[2] The accident was detected only after the residents requested that the level of radiation be measured in the apartment by a health physicist.[1] Part of the wall was removed and sent to the Institute for Nuclear Research (NASU), where the cesium capsule was removed and disposed of.[1]

The total number of deaths is alternately reported as 2[3], 4 (3 children and one adult)[1], or 6 (4 children and 2 adults)[2].
