DRINKING WATER
Drinking water was loaded by each ship before departure from Tokyo
‘and their supplies replenished following arrival at Rabaul.
Half~-liter
samples of the original drinking water loaded at Tokyo, and, also, mixed
Tokyo and Rabaul water samples from different tanks were collected.
The
analysis for gross beta radioactivity was conducted by Task Unit 6 of
Task Group 7.1 at Eniwetok Proving Grounds.
The results are as follows
(see Tab D, Appendix III and IV):

These results show no evidence of redioactive contamination.
the
preferred 30 day limit for beta activity in drinking water is 2,600
d/m/ml, and the acceptable 30 day limit is 70,000 d/m/ml.
Neither ship was equipped with a distillation unit for evaporating
sea water for drinking purposes,
