while the introduction of radioactive tracers in the study of metabolic pathways has been well-documented in clinical thyroidology as early as 1924, the widespread utilization in other clinical specialties has been hampered by slow developments in radiation-detecting devices and in the production of appropriate radiopharmaceuticals, in addition tothe morbid fear of radiation. in the philippines...

Health problems after a nuclear crisis are aninteresting issue in medicine. After the recentJapanese nuclear crisis, several health issuesunderwent monitoring. There are few considerationson mucocutaneous diseases. Indeed, there is nodoubt that the skin and mucocutaneous issues arethe main organs affected by leaked radiations. It isimportant to take care of mucocutaneous lesionsin acute radiati...
To many in our community the study of nuclear Physics is a mental exercise that strengthens the mind, and helps to accumulate the appropriate number of points for a BSc degree. In reality many of the fundamental concepts of Physics, and nuclear physics in particular, have led to significant improvements in the community. (ref. MRI, CAT, PET, radiation therapy, nuclear power). This paper address...
In this study, calibration process was carried out for deigned new CR-39 nuclear track detector for protons, neutrons and alpha particles separately under the same etching condition. In order to aim this purpose, americium-beryllium standard source (241Am-Be) and Plexiglas phantom for neutron irradiation, brass collimators and americium standard source (241Am) for alpha irradiation and the acce...
Antinuclear activity was assessed in serum samples from a series of 40 patients with differing clinical subsets (including renal and neurological disease) of systemic lupus erythematosus (SLE) against a transformed keratinocyte line (SvK14)* and normal human keratinocytes. Paired serum samples were studied during disease activity and inactivity, and the effects of ultraviolet radiation on the a...
Background: Several landmine detection methods, based on nuclear techniques, have been suggested during the recent years. Neutron energy moderation, neutron-induced gamma emission, neutron and gamma attenuation, and fast neutron backscattering are nuclear-based methods used for landmine detection. The aim of this study is to use backscattered neutron for landmine detection. Materials ...
Introduction: Individual exposure after a nuclear detonation (atomic bomb) delivers abundant doses with high dose rates to the people who were located near the nuclear detonation location or within the fallout zone. Effects of the radiation to the humans and animal models will be studied and a fundamental ground work of medical services and managing systems for such accidents wo...
