Dear Radsafe Listers,

Below is an email from a teacher in Ohio that has come across "6 small
of yellow & white powders labeled 'Becquerel Chemicals, Damon
Product #99142' by Damon Scientific Company."

I have seen this question posted before and all I have been able to
is that this is most likely a radioisotope kit for a cloud chamber.
has been encouraged at this point to at minimum borrow a Geiger counter
check the radioactivity. 

If you can help us further identify these samples please contact us
the list or directly at gregk at westgeauga.k12.oh.us (Kristen Gregory)

Thank you,

This is a follow up email to corresponce with Jim Kaufman regarding the
identification of some radioactive chemicals that I have in my

I know it's a long shot, but I was hoping that maybe you have come
across this question before. 

We need to get rid of, or at least identify, all radioactive substances
in stock as per Jarod's Law. The troublesome chemicals that I have are
in kits of 6 small boxes of yellow & white powders labeled "Becquerel
Chemicals, Damon Engineering Product #99142" by Damon Scienctific

A web search showed 2 entries by others who have these chemicals in
their storerooms, but no identification of the compounds. 

Do you have any idea what they are or where to search for an answer? 

Thank you for your help.
