Irradiation of the Bulgarian population from the Chernobyl accident

Assessments of the exposure of Bulgarian population were given by the National Centre of radiology and Radiation Protection, Sofia (BG), in 1986 and the work continued till 1992. A number of analyses relating to particular risk groups are still in progress. For the first post-accident year, the effective dose equivalents were as follows: 1.03 mSv for children aged under 16 years; 0.67 mSv for adults; an average of 0.79 mSv for the population. The corresponding exposure averaged over a lifetime is 0.95 mSv. Doses to thyroid glands amount to 10.0 mSv and 3.3 mSv for children and adults, respectively. (author)
