TL;DR: An inexpensive prototype irradiation facility is described which employs a 5 Ci Am-Be neutron source, which permits the comparison of prompt with delay gamma-ray analysis as well as cyclic activation for application to partial body neutron activation analysis.

TL;DR: In this article, the Ruark-Devol statistical density function was proposed to describe the process of radioactive disintegration where the only fundamental property is independence and stationarity are the fundamental properties that must be possessed by a physical process to obey Poisson statistics.

TL;DR: The Ruark-Devol statistical density function is shown to be satisfactory since it is capable of describing radioactive disintegration where the only fundamental property is independence and its use is recommended in both activation analysis and medical imaging when the half-life of the isotope of interest is short compared to the period of observation.

TL;DR: In this paper, the process of radioactive decay, decay and growth of radioactive species in a radioactive chain, prompt emission(s) from nuclear reactions, conventional activation and cyclic activation are discussed with respect to their underlying statistical density function.

TL;DR: In this article, the design and construction of an activation analysis system using an isotopic neutron source which allows the measurement of prompt and delay gamma-rays, in conventional activation and cyclic activation modes, is briefly described with emphasis laid on its flexibility, transportability and low cost.
