A number of fish caught after Test B were found to be radioactive. 

 By placing them overnight on photographic films, radioautographs 

 v/ere obtained, as of the surgeon fish shov/n here. Radioautographs 

 v/ere obtained of "hot" algae also. Biological procosce: have, of 

 course, no effect on radioactivity. 



The fourteen ships sunk 

 in the operation carried 

 down with them much 

 valuable information, 

 such OS instrument rec- 

 ords and various types of 

 damage to ship struc- 

 tures. Divers and under- 

 water cameras made 

 good a large part of the 

 informational gap. Here 

 is an underwater photo- 

 graph of superstructure 

 wreckage, including a 

 damaged pressure gage.
