What happened in dyatlove pass incident?

@Richard65 لbut what explains the radiation in their dead body?

@saher090 The pollution parameters on the clothing were very similar to the contamination of the Mayak nuclear accident, known as the Kyshtym disaster, which occurred in September 1957. One victim, Krivonischenko, worked at the site of the accident. Plus another victim, Zina, was from a village that was affected by the contamination. Therefore, it is very likely that their clothing was contaminated before the trip began.
