RADSAFERS, I recently ran across a large
stockpile of Florospar (CaF2 as marked) ore
that provided a reading of over 100,000 cpm on a 2x2 NaI detector. Does
anyone know what might be giving that sort of response since neither
Ca or F, as far as I know, are radioactive? My guess is that the ore is “contaminated”
with either uranium or thorium.
Thanks for your help
