✦ Synopsis

The photon spectra and counting efficiencies of 'OYCd, rr5"Cd, z"3Hg, and 65Zn obtained by liquid scintillation counting are presented. Although these nuclides undergo multiple modes of radioactive transformation, the photon energies are sufficiently grouped within a certain energy range to allow simultaneous counting with either 3H or 'Y in double-label experiments. The simultaneous assay of 3H with "smCd and W with 65Zn was demonstrated with rat liver cytosol fractionated by gel filtration chromatography.

Benzoyl peroxide in toluene was used to bleach chlorophylls in alcohol extracts from plants fed with r4C0, for improved direct measurement by liquid scintillation counting. The 0.5% benzoyl peroxide was better than the saturated solution due to less color quenching. Increased counts occurred with al
