Large-Area Scintillation Counters [PDF]

Nature, 1950
IT is of great interest, particularly in cosmic ray experiments, to employ scintillation counters which have a large sensitive area. The first essential is a large transparent crystal. Crystals of naphthalene containing 1 per cent of anthracene and of size up to 8 in. in diameter and ½ in.

Detection limit calculation according to ISO 11929 for in vitro 210Pb radiobioassay determinations by LSC

Brazilian Journal of Radiation Sciences, 2023
According to the limit of detection (DL) presented in ISO 11929:2010, the International Organization for Standardization (ISO) abandoned the concept of minimum detectable amount (MDA) described in ISO 12790-1:2001. In this work we demonstrate and discuss

Performance of the neutron polarimeter NPOL3 for high resolution measurements [PDF]

, 2005
We describe the neutron polarimeter NPOL3 for the measurement of polarization transfer observables $D_{ij}$ with a typical high resolution of $\sim$300 keV at $T_n$ $\simeq$ 200 MeV. The NPOL3 system consists of three planes of neutron detectors. The
