In order to estimate the rate of decay between 8 and 11 March, the follor
ing radiation measurements were taken o threo days on Rongelap Island:

An area was selected 30 yards inland from tho Rongeclap cemetcry as a mas
ing point for future decay measurcments, This arca is outlined with 2X%4s plac

The waist height reading was 210 or/hr at 1000 hours, 11 March 1954
Sample collections
Water samples were collected from the water supplics of all inhabitec
arcas, About two quarts of water wore transferred to a polycthlenc bottle at
each site. Thesc will be turned over to tho New York Operations Office{ AKC f
analysis,
Soil samples wore collected at all inhabited arcas and also at severe
uninhabited
islands, In collecting tho soil samples a one foot by onc foot
square was martedon the ground and soil to about ome inch of dopth was remover
from the square and transferred to a cardboard container.
The primary sample:
will be turned over to the New York Operation Office, ASC, for analysis, and
some smaller samples will bo analyzed by Program 2 of TU 13.
Listed in Table 3 are the samples taken with the dose rato measured .
at waist hcight at the location where they wero talon.
