Tongs were not used at all by the men working with the filter
paper. I pointed out the toncs to the mean just before they started to ocollect the paper, for the purpose of being sure the men knsw where they vere.
It ia my opinion that the beta burns suffered by the men were dus
almost entirely to handling the filter peper without the use of tongs. It
is possible that contamination on the gloves from handling the filter units,
as well as exposure received during the ectual handling of the filter units,
contributed appreciably to the beta exposure. However, it should be emphasized that the surface of the filter units contained fer less active material
than did the filter papers themselves. In addition, the work performed by
Albright and myself necessitated our handling the filter units for longer
periods than the other men did. It is true that we changed gloves frequently, wo the possibility that contaminated gloves were a factor in promoting
excessive beta exposure to the hands of the other men cannot be eliminated.
After the yoke and rebra operations all of the men took showers and
changed their clothes.
Ho survey was made of alcthes until after this change.
The Rad Safe monitor checked the clothing of the man before they embarked
on the sample planes, The monitor also checked my hands. Wo apprecieble
contamination vas found in these surveys.
