Shervonuk L. The development of construction and technological process manufactoring special footwear with radiation.

The desertation is devoted to the problem of the development of constructions of special footwear with radiation - protective properties for the people working in the radiation - contaminated zones, for the people working in mining industry. The influence of titanium salts in the tanning solution and leather density on beta / gamma rays - radiation - protective properties has been determined as well. After carring out research the following results have been odtained. The influence of radiation on physical and mechanical properties of the leather made from hides has been determined. The construction of special radiation - protective footwear has been designed. The technological processes of shoe closing and manufacture have been improved. The rational conditions of upper formation at minus / plus changing temperatures and two-layer materials in packets have been determined.The hygienic properties for new footwear have been investigated and the recomendations its usage have been made.
