Half Value Layer calculations theoretically need prior specification of linear attenuation calculations, since the HVL value is derived by dividing ln(2) coefficient. The purpose this study was to establish a direct computational model for determining HVL, vital parameter in nuclear radiation safety studies and shielding material design. Accordingly, typical gamma-ray transmission setup has bee...

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...

Alanine's relative response to kilo-voltage X-rays, compared 60Co reference quality beam, was studied in this work, order determine correction factors be applied alanine's when irradiated with low medium energy X-rays (up 300 keV). The of Aerial's alanine dosimeters determined by three distinct methods: experimental measurements using and a calibrated PTW Farmer 30013 ion chamber, Monte Carlo s...

Precise metering of the void fraction is one important problems in oil, chemical and petrochemical industries. For measurement, there are different kinds sensors with configurations. In this regard, capacitance-based sensor gamma-ray attenuation-based very well known as two most accurate widely used sensors. paper, we report, to best our knowledge, for first time a comparison between these an a...

Fast spectrum reactors are essential for the future of nuclear energy. Therefore, there is a need continuous research and development design safety current fast reactors. The aim this work to analyze process fuel burnup in large scale (3600 MWth) Sodium cooled Reactor (SFR) core. This called European (ESFR). It proposed 7th Framework Programme within Euratom Framework. A new version (version 2....

Commercially there is a growing interest in applications of neutrons. Currently the majority of neutron sources are based at research institutions from either reactors or spallation sources. Smaller portable sources contain either fissile isotope or sealed fusors are available, although they either use or produce tritium, or other long lived decay products. As an alternative to the large facili...

Abstract Simulation of the new exposure room shielding for Neutron Radiography Imaging (NURI) at 1 MW PUSPATI TRIGA MARK II (RTP) nuclear research reactor in Malaysian Nuclear Agency, Malaysia has been presented this article. Previous to be disassembled due various reasons such as radiation streaming problem and outdated since was constructed 1985. The NURI facility had undergoing major upgradi...

The Legnaro National Laboratories (LNL) of the Italian National Institute of Nuclear Physics (INFN) are developing a neutron source within the SPES-BNCT project. An accelerator-based, high-flux thermal neutron beam facility is planned for the experimental treatment of skin melanoma. Neutrons are produced via the Be(p,n) reaction by bombarding a 1 mm thick beryllium target with 5 MeV protons gen...
