[en] The incorporated radioactivity arising from the Chernobyl reactor accident has been measured by whole body counter on 4 persons coming from Eastern European countries, among them one from Kiev, and on a person living near Chernobyl, in August 86. According to the results computer, the highest ¹³¹I intake (in Kiev) corresponds to 92,5 kBq (2,5μCi); incorporation in a foetus was demonstrated and the whole body activity expressed in counts/m² body surface was not proportional to the distance between the place of residence and Chernobyl. Use of 'iodine pills', change in alimentary habits and the fact of leaving the contaminated zone sooner, diminished altogether the absorbed radioactivity. 10 refs
