Insight into radiation damping of an unbounded medium is developed by addressing the relative contributions of the elastic restoring force and the inertial force at infinity. When the inertial force dominates, radiation damping occurs. When the elastic restoring force dominates, no radiation damping arises.

Critical Care Clinics, 2005
The US Department of Homeland Security, and other state and federal agencies, continues to express concern over the potential use of radioactive isotopes as a weapon of terror. Few emergency medicine and critical care physicians are familiar with the care and treatment of an accidentally or intentionally irradiated patient who is contaminated ...

Radiation biology and radiation protection
Annals of the ICRP, 2012For protection purposes, the biological effects of radiation are separated into stochastic effects (cancer, hereditary effects) presumed to be unicellular in origin, and tissue reactions due to injury in populations of cells. The latter are deterministic effects, renamed ‘tissue reactions’ in the 2007 Recommendations of the International Commission on

Ionizing radiation has sufficient energy to break chemical bonds and produce charged ions in living tissue. These changes may cause cell death, but breaks of both strands of a DNA molecule that do not kill a cell may be a precursor of cancer. Excluding medical exposures, natural radiation accounts for most human exposure, which produces ...

Radiation and Radiation Disorders
2019With current technologies, radiation doses associated with exploration and habitation missions to the Moon and Mars may well exceed the limits currently defined for LEO operations. Assessment of the radiation protection needed during interplanetary and remote planetary missions should include consideration of several key technologies, such as ...

Ionizing radiation and radiation protection
2017Ionizing radiation has been revolutionizing the diagnostic process in medicine. However, its use is not without risk, necessitating protection of patients and staff from potential harm. The amount of radiation patients receive continues to rise, mainly due to the use of high-dose examination techniques such as computed tomography and image-guided ...

Radiation Physics and Radiation Safety
2015Abstract One of the fundamental quests of nuclear cardiology is the search for elements with appropriate chemical properties for use in radiopharmaceuticals, which have radioactive isotopes that produce photons well suited for imaging, and deliver only a small radiation dose to the patient.
