The radiobiolo9ical laboratory. Here investigations are conducted on pollution problems that can arise from 

 the disposal of radioisotopes and fission products in the ocean. These problems arc being studied in relation 

 to the effect of nuclear wastes on the physiology and metabolism of marine organisms 



In addition to the equipment usually found in 

 marine biological research laboratories, special 

 equipment for radiobiological research has been 

 installed. It includes stainless-steel fume hoods, 

 radioactivity-survey meters (better known as 

 Geiger counters), and scalers connected with 

 Geiger-Miiller tubes or scintillation heads for 

 measuring beta and gamma rays. The laboratory 

 also has physiological and biochemical equipment, 

 including photometric instruments and a Warburg 

 respirator; and it has facilities for culturing bac- 

 teria, planktonic algae, and other marine organ- 

 isms. Air conditioning protects the delicate lab- 

 oratory instruments from the damaging effects of 

 the humidity and the salt air.
