Re: Item Identification

     This kit has been arround in one form or another for perhaps three 
     decades. The original contained lettered plastic cubes with a gram or 
     two of uranium sulfate, sodium sulfate, uranium nitrate, sodium 
     nitrate, thorium nitrate, and sulfur. The lettered cubes were placed 
     on a sheet of film for three days. By observing which cubes fogged 
     film, the student could deduce which elements were radioactive and 
     then confirm with a Geiger counter. The current version of this kit 
     substitutes small plastic bags of the same chemicals and is available 
     from various educational supply catalogs.

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.
