2.

The Chemist will pick 10% of the samples and the following analysis will be
performed. Where GZ samples are involved, one shall be a surface sample.
(1)

Record total wet weights, wet volume and total dry weight.

(2)

Dry and balimill all samples selected.

(3)

Run gross alpha, Pu-chemistry, and gamma scan on all selected samples. Run

(4)

If samples are from GZ areas, run one surface sample for isotopic uranium.

Am-chemistry on one sample out of group.

Report (DOE/Data Reduction):
a.

b.

Gross alpha on dry rough soil will be done on all samples.

Wet weight, dry

weight, wet density, gross alpha, 238py, 239,240py, 2414m

by gamma and 241Am by chemistry on 10% selected.

e.

Isotopic uranium on surface GZ sample.

d.

Data from the label, raw data, results, calibration data and all gamma spectrums
generated will be stored on magnetic tape and sent to DOE/Data Reduction for
permanent storage.

Cc.

FRST Team Samples.

FRST samples are collected by FRST field crews in support of FCDNA operations.
1.

FRST samples are not ballmilled and typically will not be analyzed for more than dry
gross alpha. Additional analysis will be requested by FRST on a case-by-case basis after
gross alpha data is received.

2.

Report (FRST Team with copy to DOE/Data Reduction):
a.

V.

All gross alpha and other data as required.

Procedure
A.

Soil samples are received in 1/2-and 1-gallon cans furnished to field crews by EIC supply. As
sample cans are received at the sample preparation facility, they should be checked to assure
that metal labels are affixed and complete field data is written in.

B.

The sample is sereened on the FIDLER to estimate its 2414m content.
1.

If pCi/g of 241m is <60, proceed to Step C.

2.

If pCi/g 241Am jis 260, do not open ean. Notify chemist who will estimate gross alpha
based on previous samples or other island data. If his estimate indicates gross alpha to
be less than 400 pCi/g, proceed to StepC.

3.

If sample gross alpha estimate is greater than 400 pCi/g, then handle by high level

procedure (DOE/ERSP Procedure No. 16), after obtaining DOE/ERSP Project Manager's

approval.
Cy

Homogenize sample by stirring with a disposable spoon and take a random portion of rough soil
and dry. Spread approximately 50 grams of dry soil evenly in an AC-3 plastic cover, place a
spacer on top and take a gross alpha reading.
