Abstract
Detector dead time, caused by both the physical attributes of the the detection process and the electronic registration system, is perhaps the most prominent effect in non ideal detector behaviour. Although it has been studied intensively in the past and recent years, there are still many unresolved issues, that are likely to affect future methods, such as fast neutrons multiplicity counting. In the talk, we will introduced recently published results concerning a Central Limit Theorem (CLT) approximation to the detector count distribution under several dead time models, and discuss their applications to radioactive measurements. In particular, we will consider applications in Neutron Multiplicity Counting (NMC) and multi component detector systems.
