The share of the activity of Sr 90 and Tritium played only an insig- 
nificant role in the Fallout. The share of Sr 90 in the Fallout was

the deviation range of the values ascertained before the accident. 
The activity concentrations of Cm 242 surmounts those of Pu 239. The 
daughter isotope of Cm 242 is Pu 238, with a half-life of 87 years.
