Abstract
Comparative analysis of the alkaline phosphatase post-inactivation dynamics in natural and tritiated water (H2O and HTO, respectively) after ultrasonic or γ-irradiations was performed. It has been established that in HTO, unlike in H2O, the enzyme retains its activity up to 15 days. It is hypothesised that different hydrogen bond structure of tritiated water results in a lower effect of ultrasound or gamma-irradiation reactive species onto enzyme globules.
