In this paper in order to achieve a suitable spectrometer for nuclear radiation detection at room temperature, effect of adding the element Hg to binary compound semiconductor ZnTe was studied completely. Electronic structure and transport properties of ternary compound semiconductor ZnxHg(1-x)Te (ZHT) simulated using ABINIT as a computational code based on density functional theory. According ...
The verification and validation (V&V) of the Serpent 2 Monte Carlo code for 3-D reactor dosimetry applications is being carried out at VTT. Two code-to-code computational benchmark cases were calculated by MCNP 2. efficiency different variance reduction techniques was appraised. part currently includes two experimental benchmarks from SINBAD database: Pool Critical Assembly-Pressure Vessel ...
In this paper, we present a useful Monte Carlo (MC)-based methodology that can be utilized to calculate the absorbed dose and initial levels of complex DNA damage (such as double strand breaks-DSBs) in case an environmental ionizing radiation (IR) exposure incident (REI) i.e., nuclear accident. Our objective is assess doses by isolating only one component total released environment after REI wi...
The dose calculation accuracy of a commercial pencil beam IMRT planning system is evaluated by comparison with Monte Carlo calculations and measurements in an anthropomorphic phantom. The target volume is in the right lung and mediastinum and thus significant tissue inhomogeneities are present. The Monte Carlo code is an adaptation of the MCNP code and the measurements were made with TLD and fi...
Shielding calculations for industrial 5/7.5MeV electron accelerators using the MCNP Monte Carlo Code
Abstract The Cs 2 LiYCl 6 :Ce crystal (CLYC) is an inorganic scintillator which has been developed for the γ-ray and neutron measurement with high detection efficiency, resolution, no need unfolding technique. To enhance of fast neutron, CLYC 7 Li-enrichment (CLYC7) developed. In this work, response CLYC7 detector to obtained using 137 calibration source calculated Monte Carlo N-Particle transp...
In this study MCNP-4C code is used to simulate the least shielding requirements for a mammography room. In order to simulate the X-ray tube, a molybdenum target is irradiated by 28 keV electrons. Then, a molybdenum filter with a thickness of 30 micrometers was used to remove the low-energy parts of X-ray spectrum. Finally the dosimetry evaluations were conducted after designing the lead shield ...
