The study of cancer incidence is carried out in a cohort of residents of the most highly contaminated territories, who were exposed in childhood (0-14). Dramatic increase of thyroid cancer incidence rate may be caused by radiation factor. As to leukaemias and lymphomas and other forms of solid cancer,this analysis shows a lack of significant increase in their frequency. Further monitoring is expedient because of the long latency period of development of solid tumours (20 years and more).
