Re: Pure beta

Table 1-1, of "Radiation Detection and Measurement", 2nd Edition, by Glenn
F. 
Knoll (New York, Wiley, 1989) lists "Some 'Pure' Beta-Minus Sources":  H-3, 
C-14, P-32, P-33, S-35, Cl-36, Ca-45, Ni-63, Sr-90/Y-90, Tc-99, Pm-147, and 
Tl-204.  Since H-3 can appear in any compound which contains hydrogen and is 
not part of a decay chain, there is no other radionuclide that will always
be 
associated with it.   
 
The opinions expressed are strictly mine. 
It's not about dose, it's about trust.
