Monitoring of internal exposure of the population in regions close to the Chernobyl nuclear power plant

In the first month and a half after the accident, the dose burden on the population was determined by radioactive iodine deposited in the thyroid gland. Later, the dose burden was governed by caesium-134 and caesium-137. The measurements made are generally reliable. Departures from the norm in extreme cases (in the event of marked differences from the standard body build) were no more than 50% of the actual activity (at levels above 150-200 nCi). Since there is no effective method of measuring nuclides incorporated into the bodies of children, it is necessary to develop special phantoms simulating the human body at different ages.
