[ RadSafe ] looking for radioactive (calibration) sources

[KJ Kearfott]

I am looking for the following radioactive sources

1. Calibration sources for alpha spectrometers

2. Example alpha spect sources for students to use as unknowns (planchets 
preferred)

3. Sources for Buchler Irradiator (this was the old Amersham beta 
irradiator, I believe). Specifically interested in Tl-204 or Kr-85

4. Calibration sources of all types with natural uranium and thorium

5. Calibration source for radon canister system.

Thanks for considering this!
