[Some Aspects of Medical Activities to Overcome Consequences of Chernobyl Accident].

The results of the long term work of the Russian Scientific Centre of Roentgenology and Radiology on me- dical investigation of the participants in the liquidation of the consequences of Chernobyl power plant acci- dent have been summarized. It has been stated that circulatory system and tumor diseases occupy the leading position in the disease rate among the affected liquidators. The important role of cytogenetic investigation was pointed out. It allows us not only to determine the efficient impact on the human body but also to evaluate the effective dose of radiation, the information about which allows us to predict the development of distant post-irradiation pathology. The results of cytogenetic investigations testify to the interrelation between the level of chromosomal abnormalities and cardiovascular diseases and confirm the clinical data on the non- neoplastic.pathology among the liquidators of the accident.
