The field of Health Physics is devoted to the protection of humans from the adverse health effects associated with exposure to radiation -- ionizing or non-ionizing. The Health Physics program at Georgetown University offers a Master of Science degree in Health Physics. This program has two different tracks: (i) traditional health physics track; (ii) nuclear nonproliferation track. For students who select the nuclear nonproliferation track, the focus of the internships and the required courses is directed more toward the science, technology and some policy aspects of this subject. The curriculum of the Health Physics program, for both tracks, has been designed to provide students with the necessary theoretical and practical knowledge to become competent health physicists. Students in the program have the opportunity to gain valuable experience in various areas associated with health physics, such as basic radiation physics, radiation detection, radiation dosimetry, radiation and chemicial cancer risk assessment, environmental radiation protection, and radiation biology.
January 8, 2014 (CBS News). Launch of an Orbital Sciences Antares rocket carrying an unmanned Cygnus cargo ship bound for the International Space Station was scrubbed Wednesday because of high radiation levels in the wake of a major solar flare earlier this week. Liftoff from Wallops Island, Va., is on hold until at least Thursday pending additional analysis of the space weather environment. The only other launch delay in recent memory that was blamed on space radiation occurred in 2001 when a powerful solar flare prompted mission managers to scrub the launch of an Athena rocket from the Kodiak Launch Center in Alaska. In a statement, the company said the scrub was ordered "due to an unusually high level of space radiation that exceeded by a considerable margin the constraints imposed on the mission to ensure the rocket's electronic systems are not impacted by a harsh radiation environment." NASA said the lab's six-man crew was not in any danger.[MORE NEWS]
