DIVISION OF RADIATION AND ORGANISMS 

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



The research program of the Division is concerned with the effects 

 of solar and ionizing radiation on biological systems, with emphasis 

 on developing systematic concepts of the metabolic mechanisms and 

 responses of living organisms as influenced and regulated by radia- 

 tion. Areas of concentrated effort include problems relating to the 

 regulation of metabolism by radiation, the determination of structure 

 and function of macromolecules involved in energy storage, the meas- 

 urement of seasonal changes in spectral distribution of total sky radia- 

 tion and the correlation of these changes with plant responses.
