RADIOBIOLOGICAL MECHAXISM AT THi: CELLULAR LLVLL 



Mr. Jackson: I was consklcrint^ the possibility that when a cell is inacliatcd two 

 chain reactions arc initiated, one involving inorganic radicals and anotlier involving 

 organic molecules leading to a production of organic peroxides, so that the response 

 to a small pulse might be influenced by a preceding exposure to a large pulse. Could 

 this be investigated by means of your Generator? 



Dr. Gr.\y: Yes. I think it could. We ha\c many things we should like to do. I think 

 this might be illuminating.
