beta's in my coffee creamer

["H. Westenbrink" <h.westenbrink@AMC.UVA.NL>]

To my surprise I found beta's in coffee creamer, when I

counted a mixture of creamer and scintillation fluid (ultima gold)

in a LSC at 0 - 156 keV. There was a significant difference with

the blanc.

When I mix creamer with demi-water I see in the LSC at 0-19 keV

a significant difference with the blanc (cherenkov?). Only at day one



Can anybody tell which isotope I see?
