Re: Cloud chamber Source- id

[MIannaccone@DHHS.STATE.NH.US]

List:

I recently received a request for waste disposal identification/assistance

from a high school teacher who has identified "legacy" RAM.  The inf.

available indicates the items in question (twelve sources) came from a

Cloud Chamber Kit manufactured by DAMON/Educational Division, Westwood, MA

and distributed by Earth Science Curriculum Project. The only specific inf.

is:  radioactive source part number 100031.  Best guess is 15-20 years old.

Any resident knowledge (i.e. isotope, and original quantity of material)

would be helpful.

Thanks in advance,

M Iannaccone,

Health Physicist
