Two studies expanding the customary use of 3M Empore(TM) Rad Disks hav
e been conducted. In the first study, Ra-226 and Ra-228 were determine
d simultaneously by an improved method that used a single gamma-spectr
oscopy analysis. In the second study, various tracer materials and pro
cedures were used to correct for yield losses in the determination of
Sr-90 and Tc-99 in synthetic samples that contained significant interf
erences.
