DIVISION OF RADIATION AND ORGANISMS 

 Prepared by W. H. Klein, Chief of the Division 



The research program of the Division has been concerned with 

 fundamental studies in the area of radiation biology with emphasis 

 on developing systematic concepts of the metabolic mechanisms and 

 responses of living organisms as influenced and regulated by radiation. 



In the study of phototropic responses, the tropic response of Phy- 

 comyces hlakesleeanus to unilateral broad band blue (400-500 m/x) 

 light has been found to disappear at intensities greater than 1,300
