Changes in the dynamics of water metabolism in the rabbit organism as a function of external γ-radiation dose

The objective of the work was to study and describe mathematically the dependence of water exchange dynamics on the dose of external gamma radiation. An hour after exposure, tritium water was introduced into rabbits' posterior auricular veins and urine water activity was determined. The relationship between half-extraction constant of the isotope and the radiation dose of exponential type was revealed and described in the study. Quantitative ratios were obtained characterizing disorders in water exchange dynamics expressed through ratios between half-extraction periods and half-extraction constants; in the comparative control row: %300r:600r:900r they are 15:21:32:47 respectively
