ACTION OF IONIZING RADIATION ON SIMIMJ: ORGANIC COMPOUNDS 



Dr. Gray: I am interested to know experimentally uIk tht r it docs or does not and 

 which breaks most frequently. 



Dr. Duncan : It seems to me that one very important consequence of this is that there 

 are five carbon atoms and, on statistical grounds of course, one expects to be ahead 

 in the ratio of two to one. Now, the efrecls which they give, of course, are not in 

 this ratio at all, partly because one might very well get transfer of energy along this 

 chain, which is known to occur, and of which this might be evidence, and also of 

 course, because the subsequent chemical reactions which take place are not actions 

 which are purely chemical but are concerned with excited species between radicals. 

 Therefore, this kind of thing could happen in biological systems, and because of it, 

 care must be exercised in interpreting the results.
