levels of activity in samples of well water in the postoperational
period were relatively unchanged from the preoperational samples.
The gross beta levels of activity of grass samples in Table IV are
lower than those found during the operational phase, as will be
noted on the sample from Rarotonga.
During the test period, the
activity level found was 135,000 une /Ikg 3 whereas , the level in1 the
postoperational period was reduced to 15,000 ‘auc/ikg.
