PLATE 3 



1. This is a close-up view of the operation shown in plate 2. The graphite "stringer" 

 containing the holes in which the aluminum tube has been inserted for irradiation can be 

 seen in the mirror above the lead "coffin" through which the stringer is being pulled out 

 of the reactor. The operator at the left is surveying the level of radiation with a "cutie 

 pie" radiation-detection instrument. 



2. This shows a close-uc < >l i lu- k-ad "coffin" through which the stringer shown in the photo- 

 graph above will be pulled out of the reactor. Note that the operator wears rubber gloves 

 to prevent the possibility of his hands becoming contaminated. Also note that he wears 

 a film badge clipped to his collar and two pocket meters in the pocket of his coveralls to 

 measure the amount of radiation to which he is exposed during the operation.
