Sanitary and health measures taken to deal with the consequences of the Chernobyl accident

By the end of the first year after the accident, more than 20 million gamma background measurements had been made at population centres; 500,000 samples of drinking water and water from open reservoirs, and 30 million different surfaces (transport vehicles, housing, ground, clothing, etc.), had been tested. Analyses had been made of 700,000 samples of milk and milk products, 120,000 samples of meat and meat products and more than a million samples of other food products. Iodine prophylaxis was administered to 5,400,000 people, including 1,690,000 children. Temporary whole-body exposure limits of 100 mSv (50 mSv for external exposure and 50 mSv for internal exposure) were introduced for the first year after the accident, in the light of scientific data on the effects of various exposure doses and in view of the actual radiation conditions. The standard for 1987-88 was reduced to 3 rem (30 millisievert), in view of the actual reduction in exposure levels achieved as a result of the large-scale clean-up measures undertaken. (author).
