Background: Neutron contamination in our environment can cause harmful biological effects on human body. Therefore, many efforts have been made to construct a neutron dosimeter to estimate the received dose. Objective: To design a simple neutron dosimeter. Methods: The primary dosimeter had 3He as a spherical thermal neutron detector encircled by paraffin 10 cm in radius. Then, the paraffin sph...

Background: The Poly-Allyl Diglycol Carbonate (PADC) detector is of particular interest for development of a fast neutron dosimeter. Fast neutrons interact with the constituents of the CR-39 detector and produce H, C and O recoils, as well as (n, α) reaction. These neutron- induced charged particles contribute towards the response of CR-39 detectors. Material and Methods: Electrochemical...

A detection system using room-temperature, microstructured solid-state thermal neutron detectors with very low leakage current has been developed at Rensselaer Polytechnic Institute (RPI) with the ability to provide positional and spectral information about an unknown neutron source. The Directional and Spectral Neutron Detection System (DSNDS) utilizes a set of small-but-scalable, zero-bias so...

This paper describes a neutron detector designed by INFN-Sanità group of Rome. The detector ful"lls all the requirements of cold fusion experiments and, on the other hand, can operate in several kind of experiments involving neutron detection, even when signi"cant, variable and not taggable background is present. As a matter of fact, it is suitable to detect every source emitting multi-MeV neut...

This paper describes a neutron monitor which consists of a spherical neutron moderator, 12′′ in diameter, with a thermal neutron detector which detects delayed β-radiation from silver activation. The thermal neutron detector is based on four silicon diodes at the centre of the moderator, two of which are covered by silver foils, 250 μm thick, and two by tin foils, 360 μm thick. The latter two d...

A unique, new stand-alone acoustic inertial confinement nuclear fusion test device was successfully tested. Experiments using four different liquid types were conducted in which bubbles were self-nucleated without the use of external neutrons. Four independent detection systems were used (i.e., a neutron track plastic detector to provide unambiguous visible records for fast neutrons, a detector...

The BC-523A detector is a boron-10-loaded liquid scintillation detector that is sensitive to not only fast neutrons and gamma rays, but also to thermal neutrons. This detector has recently attracted the attention of several researchers and has shown promise for neutron spectroscopy. Several efforts have been made to accurately characterize this detector for several neutron and gamma-ray energie...

background: several landmine detection methods, based on nuclear techniques, have been suggested up to now. neutron-induced gamma emission, neutron and gamma attenuation, and fast neutron backscattering are the nuclear methods used for landmine detection. in this paper an optimized (safe and effective) moderating structure using an 241am-be neutron source for detecting landmines has been invest...
