obligatory condition : while producing one or other type of equation we 

 should not forget the existence of processes that play a principle role 

 in our understanding of these phenomena. Their number in our case 

 includes several additional intracellular and extracellular factors, the 

 latter being especially interesting for us. For this purpose it is necessary 

 firstly to study in detail the significance and the character of their in- 

 clusion into the radiation reaction of the organism and the dose de- 

 pendence. 



That is, w^e raise with all possible sharpness the question about the 

 rapprochement of common physiology and radiobiology.
