Radiation monitoring of various objects as part of the Chernobyl accident management programme

Permissible levels of radioactive contamination were based primarily on an experimentally established relationship for contamination in the region around the Chernobyl power plant: the gamma exposure dose rate measured close to a contaminated flat surface, 1 mR/h, is equivalent to 10,000 beta particles/cm2#centre dot#min. From this relationship, it follows that the established contamination limit of 0.1 mR/h roughly corresponds to the limit for contamination of the outer protective clothing worn by staff at nuclear power plants as laid down in the radiation safety standards (NRB-76), namely 800 beta particles/cm2#centre dot#min. Experience in establishing radioactive contamination standards and in organizing radiation monitoring made it possible to reduce significantly the adverse effects of the accident. (author). 1 tab.
