appearance to that in the Hates allout, namely, like sleked
lime.
The one iSland sample contained a solid which wes sons-
what more sandy in appearence, indicating extraneous solids
blown in by the wind.
The following quantities were determined for sone or
all of the samries: (1) Gross beta and gamma decay of all
semples, (2) Aluminum and lead absorption curves for a few of
(3) Gamma spectra for some of the samples and
the samples,
fractions thereof, (4) Oxidation state and approximate percentage of neptunium, (5) Oxidation state of iodine, (6) Fractionation of gamma activity into,solid, fonic and colloidal |
constituents using centrifugation and ultra-filtration.
addition,
In
work was continued on development of methods for
the determination of induced and fission product activities of
interest.
