The Krasnoyarsk State Medical University since 1966 has been annually awarded the prize for the best scientific student work from the personal foundation bequeathed by Professor Isai Isaakovich Gitelson.

[9] From 1957 to 1961 - Senior Researcher at the Biophysics Laboratory of the Institute of Physics of the Siberian Branch of the USSR Academy of Sciences, Krasnoyarsk.

[10] From 1961 to 1981 - Head of the Laboratory of Photobiology of the Institute of Physics named after L. V. Kirensky, Siberian Branch of the USSR Academy of Sciences.

In experimental hematology, JI Gitelson developed methods for the spectrophotometric analysis of red blood cell populations in normal and pathological conditions.

[11][12] He developed a general theory of the three-stage mechanism of hemolysis, described the patterns of distribution of red blood cell populations by stability, depending on their age, the intensity of production and destruction.

For the first time, the possibility of creating a stable, controlled, closed ecosystem for humans based on continuous cultivation of microorganisms and higher plants was experimentally demonstrated.

The purpose of such systems is to support human life in space and in unfavourable conditions of the Earth: in the Arctic and Antarctic, under water, underground, in the high mountains, deserts, as well as in a polluted environment.

Development of the "Bioalarm" project aimed at monitoring the "health" of marine ecosystems and early warning of anomalies arising from anthropogenic and natural factors.
