RISDNA Strand Breaks due to low energy electrons emitting 123I and 125I radionuclides using GEANT4
In this study, the number of DNA damages including single, and double strand breaks (SSB and DSB) were calculated using the two geometric models (volume and atomic) of DNA strand. In this respect, the new advantage of ...
Neutron spectrum measurements from 1-16 MeV in beryllium assemblies with a central D-T neutron source
Beryllium has been proposed as both a neutron multiplier and as a plasma facing material
for fusion reactors, and its neutron cross section up to 15 MeV or so is consequently of considerable importance, particularly ...
Gamma Shielding Design Studies on 252Cf and 241Am-Be Neutron Sources
Abstract : The 252Cf radioisotope and 241Am-Be are intense neutron emitters that are readily
encapsulated in compact, portable, sealed sources. They have wide range of applications in
laboratories, industries ...
Shielding studies on a total-body neutron activation facility
Background: Prompt gamma neutron activation
analysis (PGNAA) is known as a non-invasive technique
capable of measuring elemental concentration in
voluminous samples in a short period of time. Also it ...
Evaluation the nonlinear response function of a 3*3 in NaI scintillation detector for PGNAA applications
Response functions of the 3*3 in NaI detector, which is mainly used in PGNAA applications, have been calculated by using MCNP-4C code. Calculated results are compared with measured data by using standard g-ray sources and ...
Response Function of a 3×3 in. NaI Scintillation Detector in the range of 0.081 to 4.438 MeV
Response functions of a 3×3 in. NaI detector, which is mainly used in PGNAA
applications, have been calculated by using MCNP-4C code. Calculated results are compared
with measured data by using standard γ-ray ...
Geant4.10 Simulation of Geometric Model for Metaphase Chromosome
In this paper, a geometric model of metaphase chromosome is explained. The model is constructed according to the packing ratio and dimension of the structure from nucleosome up to chromosome. A B-DNA base pair is used to ...
Development of a Bonner sphere spectrometer with emphasis on decreasing the contribution of scattering by using a new designed shadow cone
In this study, the Bonner sphere spectrometer (BSS) used for measurement of neutron spectra based a BF3 long counter. The most important problem for this system was a high count of scattered neutrons. This spectrometer was ...
Evaluation of response matrix of a multisphere neutron spectrometer with water moderator
Neutron energy responses of water sphere spectrometers (WSS) to 30 MeV have been
calculated by means of Monte Carlo calculations, using the computer code MCNP4C with ENDF/B-VI.0 neutron cross-section. The calculations ...
MEASUREMENT OF THE NEUTRON SPECTRUM BY THE MULTI-SPHERE METHOD USING A BF3 COUNTER
The multi-sphere method, a neutron detection technique, has been improved with a BF3 long
cylindrical counter as a thermal detector located in the center of seven spheres with a diameter
range of 3.5 to 12 ...
