[ RadSafe ] Polonium-210 poisoning

[radbloom at comcast.net]

I think you mean Tl-208, 2.6 MeV (4N series, i.e., Th-232...Ra-228...); not Tl-206, photon emissions less than 1% of the time, 0.803 MeV maximum (4n+2 series, i.e., U-238...Ra-226...).

Well they originally thought it was Tl206, which has that big gamma line up in the 2.2MeV region because there was some weak gamma, thats the decay series of one of the Radiums , 228 I think. That would fit with a kitchen operation. But I didnt hear about any reactor gamma nuclide . This is from memory but its one of the Tl s

Do I not recall some gamma spec (yes gamma) was done which linked it to reactor based production (based on impurities) ?
