DETAILS

Radionuclide Concentrations in Sediment Samples

,

on March 20, 1974, four sediment samples (three from Oyster Creek and

2,

,r'

one from Forked River) were split for analysis by both Bureau of Radio"

logical Protection State of New Jersey and by USAEC, Idaho Health

Services Laboratory.

The results of these analyses are appended to this

report as Attachments I and II, respectively. The results of the

two laboratories are in essential agreement for the major radionuclides

present, i.e.,-for Ce-144, Cs-134, Cs-137, Mn-54 and Co-60.

The K-40

levels were not reported by New Jersey but comprise a major portion of

the total activity at each of the sampling locations. The nuclide

activities reported for the Forked River sample were lower than those

for Oyster Creek. Part of this difference can be attributed to the

smaller amount of silt in that sample. The Forked River sample was

visibly more gravelly in nature, lacking the silty sediment and organic

'

materials present in the Oyster Creek samples. The smaller amount

of natural K-40 found in the Forked River sample reflects this differ-

ence, as seen in Attachment II.
