Monitoring internal contamination of V-1 nuclear power plant personnel during refuelling

The system and results are presented of monitoring the internal contamination by radionuclides of those workers of the Bohunice nuclear power plant who took part in refuelling the 1st and 2nd unit of the power plant in 1981. Presented is the composition of contaminants, the depos:ts of radionuclides in workers with the highest internal contamination, and working procedures which most frequently caused contamination. During the work connected with refuelling and the overhaul of the plant, the level of 1/20 of the maximum permissible annual intake was not exceeded in any single worker. (author)
