The laboratory was founded in 1956 year. First chief of the laboratory was the famous scientist, doctor of chemical sciences, professor, honoured worker of Georgian science Helen Nanobashvili.
The researches were carried out in the following direction:
Radiation-chemical method is among the methods of desulfurization. Hereafter the researches were developed in two main directions: 1. Radiation chemistry of organic sulfur compounds as radioprotectors and 2. Radiation-chemical synthesis of organic sulfur compounds. Low-molecular aliphatic thiols and thiocyanates were selected as new radioprotectors. Dialkylsulfides were proposed as new dosimetric systems in the wide range of the doses.
On the basis of the fact that radiation action, as a rule, is accompanied by formation of considerable amount of ozone from air, which is characterized by high oxidation ability and makes a definite contribution in the processes of radiation-chemical transformation, the study of ozone separate action on various systems became necessary.
Important practical results obtained by the use of ozone method:
Disinfection of the sewage of isolation hospitals and purification of other industrial sewage. Obtained preliminary results allow conclude that the ozone method is characterized by high efficiency. This fact was confirmed in the course of treatment of a number of diseases and of infected wounds. The corresponding Patent was obtained.
At present the researches are conducted in the following directions:
It was established that the use of bacterial fertilizers causes a significant increase of the crop capacity of such important cultures as soya, lupine and clover (up to 22% by grain and up to 100% by green mass). Sterilized peat, so-called gamma-rizotorhin, is characterized by high quality. Its use causes a significant economy of raw material and electric power.
Radiation sterilization of materials-devices or medical purpose is of a special interest. There is now alternative of this method.
