Scintillation counting of beta activity on filter paper, with monoiso-propylbiphenyl as a solvent of low volatility, was investigated. The method is attractive since no sample preparation is involved, ...

Very low backgroud detectors are required to identify rare events, including solar neutrinos, searches for dark matter, double beta decay events, and searches for proton decay. Liquid scintillation ...

FILTER paper is frequently used as a means of supporting radioactive substances, such as proteins or the effluent from a column, for counting in liquid scintillation counters. While this is ...

WE have investigated the significance of absolute counting-rate in the scintillation measurement of gamma-rays from radium-226, iodine-131, cobalt-60 and sodium-24.
