Co-60 source wanted ~1.0uCi

[Conor Whyte]

I am in need of a ~ 1.0uCi Co-60 source for high energy calibration. Ideally a disk source would be nice.
Anyone with a spare?

The only address I know beside the officials is https://www.ebay.de/str/dosimetersradiometersdetectors he sometimes sell Ra, Am, Pu, Cs, Sr, Co ... all russian branded and nobody knows exactly activity, date of manaufacturing and stuff like this, so you may buy a piece of metalshielding with nothing countable inside.
So the officials: https://www.spectrumtechniques.com/exem ... e-sources/

Here is another supplier:

I've ordered from them in the past, they are reasonably priced.

It is my understanding that most of the re-sellers of small exempt disc sources (e.g., United Nuclear and Imagesco) obtain their sources from Spectrum Techniques. The price for most 1 uCi sources has been $50 plus some shipping charge. I haven't seen the 2023 price list yet.

The activity is said to be plus or minus 20 % of that stated. A date (month & year) is printed on the source. Turn around on the souces is pretty fast.
