Re: Item Identification


I ran across a box that contained about a dozen of these kits-what a mess
as some of the kits were leaking powder. Gamma isotopic analysis showed
U-238 and Th-232 (and their associated decay series). Frisks (GM pancake at
1 cm) of areas where the  powder had spilled ranged from 2200 to 15000 cpm
> bkg. The floor under the box was also slightly contaminated with Th-232
at 200 to 400 cpm > Bkg.

Subject:  Item Identification


I'm attempting to identify and date a source kit that I came across.

The kit is made by Macalaster Scientific Corp and is labeled as product
number 30145.  The small 7.5 x 5x2.5 cm plastic box contains six smaller
plastic boxes each labeled A-F.  Each contains a couple grams of powder.
One
is probably yellowcake and the other is likely green salt and a third one
appears to be potassium chloride.  At least 2 of the 6 are not radioactive
and one appears to be table salt.  I wish I could be more specific but
didn't
take notes when I was examining it and I don't currently have it in front
of
me.

I got the source kit from a high school science teacher because I
volunteered
to leak test it for her.

The source kit appears to be a set of "unknowns" that students are to
identify.

Any info as to the actual compounds and a production date would be useful.

Thanks in advance.
