Radiation has two meanings in physics. The first refers to propagating energy, and sometimes to the energy itself. An example is a light wave--its photons each have energy. The second meaning is the process of a body emitting energy, as in a pipe...
The term radiation broadly applied to a class of physical phenomena that share a characteristic loss of energy in the radiating body or system that results in a propagation of particles and/or waves that carry the ability to do work and thus change the...
Radiation is everywhere. Life would not exist on Earth without radiation from the sun. Additionally, many important technological activities are based on radiation, such as radio and telecommunications. Another type of radiation is used for producing...
Radiation, as used in physics, is energy in the form of waves or moving subatomic particles. Radiation can be classified as ionizing or non-ionizing radiation, depending on its effect on atomic matter. The most common use of the word "radiation" refers...
Although most are invisible, emanations of particles and waves profoundly influence all living things, including people. I picked up a Time magazine on the plane back from a long business trip. To my surprise and dismay, the obituary of Richard Marsh was printed...
Nursing and radiology staff members can have a difficult time coexisting and communicating as they strive to provide quality care for patients. Misconceptions about safe radiologic practice within the practice of perioperative nursing occur because members of these professional fields are unfamiliar with each...
A week or two of radiation to the head helped keep a very deadly form of lung cancer from spreading to the brain, improving survival for some people who have had little hope of successful treatment until now, Dutch doctors reported Saturday.It is the first...
When prostate surgery fails to remove all traces of cancer, men face a decision about whether to have radiation therapy. Radiation can lead to bowel and urinary problems, but patients might find that risk acceptable if there were evidence it...
