Synergy of Organic and Inorganic Sites in 2D Perovskite for Fast Neutron and X‐Ray Imaging
Advanced Functional Materials, 2023Fast neutron and X‐ray imaging are considered complementary nondestructive detection technologies. However, due to their opposite cross‐sections, development of a scintillator that is sensitive to both fast neutrons and X‐rays within a single‐material ...

Hydrogen-Rich 2D Halide Perovskite Scintillators for Fast Neutron Radiography.
Journal of the American Chemical Society, 2021A fast neutron has strong penetration ability through dense and bulky objects, which makes it an ideal nondestructive technology for detecting voids, cracks, or other defects inside large equipment.

The Lancet, 1972
This paper discusses the rationale of fast neutron therapy and presents some early results obtained at the Medical Research Council's Cyclotron Unit at Hammersmith Hospital, London. The importance of the oxygen enhancement ratio for fast neutrons is considered, together with the significance of the small proportion of anoxic cells present in most ...

Fast neutron and gamma ray pulse shape discrimination in EJ-276 and EJ-276G plastic scintillators
Journal of Instrumentation, 2020In this paper, we report on the scintillation properties and pulse shape discrimination (PSD) performance of new plastic scintillators, EJ-276 and EJ-276G . Cylindrical samples with dimensions of 1×1 inch and 2×2 inches were tested.

Review of Scientific Instruments, 1949
A simple fast neutron detector suitable for health physics applications has been constructed using two 931A photo-multiplier tubes in coincidence to reduce background. A ``sandwich'' made of Lucite and activated zinc sulfide is used to produce the scintillations.

This paper summarizes the recent work on fast neutron dosimetry done by the Health Physics Division of the Oak Ridge National Laboratory. Neutrons do not ionize directly, but by various reactions with tissue they produce particles which do ionize. In the case of fast neutrons the important reactions are the elastic collisions with hydrogen, carbon ...
