Protective measures to reduce population exposure doses and effectiveness of these measures

Basic measures to protect the population from radiation after the Chernobyl accident included: (i) monitoring of radiation conditions and exposure doses to the population; (ii) temporary or permanent evacuation of certain population groups; (iii) iodine prophylaxis; (iv) limitation of the intake of radionuclides with food products; (v) decontamination of land and buildings; and (vi) educational work and sanitary instructions to the population. More than 5,000,000 measurements were carried out on different objects. In some population centres external doses exceeded level A, reaching 0.3-0.4 Gy, but nowhere did they reach the upper level B. More than 70,000 farms were decontaminated an a total of about 200,000 m3 of contaminated soil was removed from large areas, taken away and buried. In 1987, as a result of these effective measures, the contribution to the dose from internal exposure averaged only 10-30%. The overall effectiveness of the protection of the population living in the zones of radioactive contamination can be expressed in terms of the conservation of 7,000 man-years of normal life.
