An area was selected 30 yards inland from the Rongclap cemctcry as a mas’.
ing point for future decay measuremonts,
This arca is outlined with 2X%4s placc.

Sample collections
Water samples were collectcd from the water supplics of all inhabitce
areas. About two quarts of water were transferred to a polycthlenc bottle at

uninhabited islands,
In collccting tho soil samplcs a one foot by one foot
square was markedon the ground and soil to about one inch of depth was removed
from the square and transferred to a cardboard containcr,
The primary samplcs
will be turned over to the New York Operation Office, 435C, for analysis, and
some smaller samples will be analyzed by Program 2 of TU 13,
Listed in Table 3 are the samples taken with the dosc rato measured ..
