ENERGY LOSS AND BIOLOGICAL EFFECTS 



Fig. 3. Section irradiated for 6 miii. Many more cytoplasmic "spot" areas appear. 

 In this section the darl^er cells fluoresce green because of a lower concentration of 

 dye. The dye has migrated to the affected cytoplasm along the length membranes. 

 The affected areas are the darkened segments between cells. The original fluores- 

 cence here was deep brick-red. 



Fig. 4. Irradiated for 10 niin. Only two or three eeila show the "control" appear- 

 ance. These are the cells that are uniformly dark, and which in the original had an 

 overall orange tint. Most cells fluoresce green and are depicted as light gray. There 

 are many spots along the cell membranes in the cytoplasm. The nuclei have here 

 also been affected and are swoUen.
