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 cosmic-ray method for measuring soil moisture, used in the Cosmic-Ray Soil Moisture Observing System (COSMOS), relies on the exceptional ability of hydrogen to moderate fast neutrons. Sources of hydrogen near the ground, other than soil moisture, affect the neutron measurement and therefore must be quantified. This study investigates the effect of atmospheric water vapor on the cosmic-ray p...

This paper discusses the variety of teaching methods employed by the Nuclear Department in the education and training of nuclear practioners in support of the United Kingdom’s Naval Nuclear Propulsion Programme (NNPP). Reactor physics is required to be taught at a variety of levels from introductory principles to postgraduate, a variety of teaching methods are employed to satisfy this requireme...

This work illustrates a methodology based on photon interrogation and coincidence counting for determining the characteristics of fissile material. The feasibility of the proposed methods was demonstrated using the Monte Carlo-based MCNPX/MCNPPoliMi code system capable of simulating the full statistics of the neutron and photon field generated by the photon interrogation of fissile and non-fiss...

UNLABELLED The ability to estimate absorbed doses in experimental animals to which radiolabeled material has been administered may be important in explaining and controlling potential radiation toxicity observed during preclinical trials. Most previously reported models for establishing doses to small animals have been stylized and mathematically based. This study establishes dose factors for i...

Nuclear logging is one of most important logging services provided by many oil service companies. The main parameters of interest are formation porosity, bulk density, and natural radiation. Other services are also provided from using complex nuclear logging tools, such as formation lithology/mineralogy, etc. Some parameters can be measured by using neutron logging tools and some can only be me...
