Radiation protection regulations have been established to reduce exposure of individuals to acceptable safe levels. These limits assume that people have similar responses to ionizing radiation and that there is no variation in individual radiation risk. The purpose of this research was to determine if apoptosis in lymphocytes can be used to assess individual sensitivity to ionizing radiation. B...

This paper proposes a physics based degradation modeling and prognostics approach for electrolytic capacitors. Electrolytic capacitors are critical components in electronics systems in aeronautics and other domains. Degradations in capacitor and MOSFET components are often the cause of failures in DC-DC converters. For example, prevalent fault effects, such as a ripple voltage surge at the powe...

background: ct scan and nuclear medicine exams deliver a great part of medical exposures. this study examined professional radiation hazards in ct scan and nuclear medicine workers.   methods : in a cross sectional study 30 occupationally exposed workers and 7 controls (all from personnel of a laboratory) were selected. physical dosimetry was performed for exposed workers. blood samples were ob...

Introduction: GATE (Geant4 Application for Tomographic Emission) is a Monte Carlo simulation platform developed by the OpenGATE collaboration since 2001 and first publicly released in 2004. In Geant4, each physics process is described by a model (several models are sometimes available for a given physics process) and a corresponding cross-section table. All Geant4 physics model...

Physics and Society is a quarterly newsletter of the Forum on Physics and Society, a division of the American Physical Society. It is distributed free to members of the Forum and to physics libraries upon request Physics and Society presents articles and letters on the relations of physics and the physics community to government and society, on the social responsibilities of scientists, and on ...
