A systematic evaluation of activity concentrations of 3H, 63Ni and 14C by using the CIEMAT/NIST method has been carried out over time intervals of 4, 2.4 and 2.3 years, respectively. It proves that the CIEMAT/NIST method can compensate, with no need

A temperature-dependent effect is reported which concerns only DIN-based liquid scintillation cocktails when they are quenched with CCl4. The poor solubility of CCl4 at concentrations over 0.3% causes a slow decrease of the quenching parameter, which

An iterative method, an analytical approximation and a Monte Carlo-based model have been intercompared by calculating the probability distribution of electrons at the output of any dynodic stage of a photomultiplier tube (PMT). All three methods acco

The currently accepted value of 163.8±1.8 d for the 45 Ca half-life is based on the two most accurate measurements of 162.6±0.1 d and 165.1±0.7 d, which are nevertheless discrepant. New measurements have been carried out using a liquid scintillati
