Radiation from the higher-energy end of the ultraviolet spectrum, in addition to X-rays and gamma rays, is known as ionizing radiation: It is energetic enough to be able to knock electrons off of atoms, turning the atoms into ions. Ionizing radiation can damage DNA and cause a multitude of...
Learn the definition of radiation and understand the causes of radiation. See the various types of radiation with examples and discover its harmful...
Fast and accurate repair of genomes is essential in surviving doses of ionizing radiation which is accomplished in radiophiles through the use of the nucleotide excision repair pathway. Other forms of oxidative stress prevention and tolerance mechanisms include cell cleaning through the elimination of ...
Studies of ionizing radiation effects through the archiving of data began with standardizing medical treatments in the early 1900s shortly after the discovery of X-rays. Once the breadth of the delayed effects of ionizing radiation was recognized, the need for long-term follow up became apparent....
Radiation is a word that has a lot of meanings. The light from a light bulb is a form of radiation, and some of the heat emanating from a bowl of soup is also radiation. But the term background radiation usually refers to a specific type of radiation: ionizing radiation. View...
Detection of ionizing radiation When radiation ionizes a gas, an ion pair is formed. An ion pair is constituted by a free electron and a cation (positively charged ion). The detector in the ionization chamber detects the nature of the radiation (like X-rays, alpha, beta, or gamma) by ...
However, since there is no ionizing radiation, this is a preferable option for many (elderly, children, etc.) A whole-body scan is roughly 25-30min for scan and 3 hours to analyze via computer software. Bioelectric Impedance Analysis (BIA) Bioelectrical Impedance Analysis (BIA) is a ...

Non-ionizing radiation: This is the release of energy from the lower-energy region of the electromagnetic spectrum. Sources of non-ionizing radiation include light, radio,microwaves, infrared (heat), andultraviolet light. Ionizing radiation: This is radiation with sufficient energy to remove an elect...
