RESUMO
The effect of the living organism on the polymer materials used for the manufacture of grids for implants. It is shown that the recipient's body is actively working to exogenous material , destroying its surface layer and forms around the implant insulating fibro-connective tissue capsule, the thickness of which depends on the severity of the organism's reaction to a foreign body. Proposed instrumental method of determining compatibility before surgery implant material with the recipient using an atomic force microscope (AFM).

The paper presents late outcomes of radiation exposure of 3205 children aged 6-17 years from native persons residing in the areas exposed to radiation 40 years ago. The spread of noncommunicable diseases in the children from the polluted area is 92%. Organic abnormalities are prevalent among them. These include thyroid hyperplasia, lymphadenopathy, gastrointestinal, cardiovascular, and other diseases. Thus, the environmental radiological situation in the southern Urals and the Orenburg Region is poor.
