Cerenkov counting and liquid scintillation counting for the determination of 18F

Creators

Description

The positron emitted (E/sub max/ 635 keV) upon radioactive decay of 18F has been used to measure 18F in liquid scintillator solutions which have low or high water capacity, and in hydrophilic and hydrophobic liquids which have different refractive indices. The influence of nitromethane, a chemical quenching agent, on counting efficiency in each of these liquids has been measured, and is discussed on the basis of observed shifts in the pulse height spectra. The contribution of coincident Compton events arising from the annihilation gamma rays, to the overall counting efficiency, has been estimated using methyl salicylate as the counting medium
