PROBLEMS OF MEDICAL EXPERTISE FOR DISEASES THAT BRING TO DISABILITY AND DEATH AS A RESULT OF RADIATION EXPOSURE INFLUENCE IN CONDITIONS OF THE CHERNOBYL CATASTROPHE IN REMOTE POSTACCIDENTAL PERIOD.

Background: The Chornobyl catastrophe (ChCt) resulted in radiation exposure of great quantity of people. Amongthem there were personnel of Chernobyl NPP (ChNPP) and workers of supporting enterprises, radiation protectionprofessionals, clean-up workers of different specialties including military personnel that were send for liquidationof its consequences, inhabitants of the Prypyat city and Chernobyl 30km exclusive zone (including children) thatwere evacuated during first days after accident and population of radioactive contaminated territories. Loss ofhealth, disability and death as a result of radiation exposure influence in conditions of the ChCt under discharge ofprofessional, military or official duties and/or living on radiation contaminated territories not by his own fault callfor developing of special form of medical expertise as part of medical social protective system for this contingents.

The morphological changes of mucous membrane of stomach and duodenum of contractor organization personnel, which works in radiation hazard conditions at the object Shelter of Chornobyl NPP.

Unlabelled: Аim: The determination of morphological features of stomach and duodenum mucous of membrane (MM) damage at a personnel that works in radiation hazard conditions at the object of "Shelter" of Chornobyl NPP (OS) by the endoscopic monitoring with biopsy material inspection from a gastro-duodenal zone on the stages of check - in (InC) and the special medical control (SpC).

Materials And Methods: the complex clinical-endoscopic and morphological examination with the biopsy of MM of stomach and duodenum in 126 workers of OS (man in the age from 20 to 59) was carried out. Doses of external radiation exposure were from 0,14 to 79,6 mSv, доза internal radiation exposure were from 0,1 to 3 mSv/Results: For the personnel of OS contract organisations differently directed pathomorphological changes of MM at InC and increase of frequency of their exposure at an inspection during SC, that generally correspond to chronic H.

Structure of comorbid diseases in patients with non-alcoholic fatty liver disease, exposed to ionizing radiation as a result of the Chornobyl NPP accident.

Objective - to study of the structure of comorbid diseases in patients with nonalcoholic fatty liver disease (NAFLD), exposed to ionizing radiation due to the Chornobyl accident, and in the groups of comparison. Materials and methods. Array of surveyed males was divided into 4 groups: the main group - 136 patients with NAFLD affected by the Chornobyl NPP accident, the first comparison group (І CG) - 28 affected by Chornobyl NPP accident without liver disease, the second comparison group (II CG) - 50 patients with NAFLD not exposed to factors of the Chornobyl disaster, and the third comparison group (III CG) - 16 unexposed persons without liver disease.

Radiation protection and health of personnel of contracting enterprises participating in works for transformation of the object "shelter" of SSE Chornobyl NPP into an ecologically safe system.

Unlabelled: Transformation of the object "Shelter" (OS) of SSE Chornobyl NPP into an ecologically safe system is one of the most important state programs in Ukraine. Both medical and dosimetric measures on healthcare of personnel participating in these works ranks the main place among most actual problems of contemporary clinical radiobiology, radiation hygiene, and radiation protection. The study objective was to work out and implement the medical and biophysical checking of the health status and workability both with radiation protection of personnel executing works on transformation of OS into an ecologically safe system.
