CAN CHRONIC RADIATION BE RADIOPROTECTIVE FOR PLANT SUBJECTS EXPOSED TO THE INHIBITING ACTION OF ACUTE GAMMA RADIATION?

Abstract

A new classification of types of radio-modifying effects is proposed, both in terms of the sequence of action of the main (inhibitory and hormesis doses) and modifying factors and in terms of the sign (direction) of the radio-modifying influence. The division of adaptive reactions into ordinary, hypo-, and hyper adaptive reactions is substantiated. Special attention in the work is given to the effects of positive post-radiation modification, essentially having, in the case of using ionizing radiation, the nature of radiotherapy (non-oncological), that can be conditionally called 'reverse radio adaptation'. Experimental evidence of its existence is presented, which can be the basis for the method of ‘low-dose radiotherapy’ of radiation damage.
