Abstract
The paper covers evaluation of concentration of natural and artificial radionuclides found in the soil and the bottom ground of water reservoirs. It was measured that radionuclide concentration in the soil is bigger than that in the bottom ground of water reservoirs (40K concentration in the ground equals 500 Bq/kg, in the bottom ground ‐ about 200 Bq/kg). Positive correlation was set among all types of radioisotopes. Correlation quotient between artificial radionuclide 137Cs and natural radionuclides amounts to zero.
Highlights
Most widely spread natural radionuclides are from the family of Uranium (238U), Thorium (232Th), and Actinium (235Ac) and Kalium. 137Cs dominates among durable artificial gamma radiators
The biggest part of 137Cs is accumulated in the upper layers of the soil and forest floor [1]
Radioactive substances emitted into the atmosphere become part of the general air circulation and moves all over the earth
Summary
Most widely spread natural radionuclides are from the family of Uranium (238U), Thorium (232Th), and Actinium (235Ac) and Kalium. 137Cs dominates among durable artificial gamma radiators. Most widely spread natural radionuclides are from the family of Uranium (238U), Thorium (232Th), and Actinium (235Ac) and Kalium. It takes 300 years for it to fragment completely. Due to that it migrates in various geospheres and biological links. Radioactive substances emitted into the atmosphere become part of the general air circulation and moves all over the earth. Radioactive substances precipitated on the earth surface are either lifted again by the wind or penetrate into the ground. Radioactive substances are absorbed by plants through their roots and reach human organism
