With the possible radioactive contamination of the
territory, as a result of emergency situations at
enterprises of the nuclear fuel cycle, there occurs a
task of further use of the soil for agricultural purposes.
Researches on the cultivation on contaminated areas of
fruit plants in the conditions of the Krasnodar region
were not carried out. As a result of the experiment in
the field we received experimental material on
migration and 90Sr accumulation in vegetative and
generative organs of cherry-plum. Research lasted for
8 years. The accumulation of 90Sr, placed on the
surface of the soil, in the bark, wood, leaves, and fruit
was 7,0×102
; 4,8×102
; 9,7×102
and 1.8 ×102Bq/kg.
With the penetration of 90Sr in soil at 50 cm
accumulation in the bark, wood, leaves, and fruit were:
5,1×102
; 3,0×102
; 6,9×102
; 1,4×102Bq/kg. The
experimental material obtained in the field makes it
possible to calculate the coefficients of the nuclide
transition from polluted soil to the various organs of
the studied plant and to make a forecast of the possible
use of contaminated areas for the cultivation of fruit
crops. Radioactive contaminated areas cannot be left
without proper control, since, firstly, non-planted
fields are exposed to wind and water erosion of soils,
which leads to rapid and large-scale pollution of the
environment and, secondly, if it is possible to obtain
products from such fields, this should be done for
economic reasons
