In radiobiology, the relative biological effectiveness (often abbreviated as RBE) is the ratio of biological effectiveness of one type of ionizing radiation relative to another, given the same amount of absorbed energy. The RBE is an empirical value that varies depending on the type of ionizing radiation, the energies involved, … See more The absorbed dose can be a poor indicator of the biological effect of radiation, as the biological effect can depend on many other factors, including the type of radiation, energy, and type of tissue. The relative biological … See more Typically the evaluation of relative biological effectiveness is done on various types of living cells grown in culture medium, including prokaryotic cells such as bacteria, simple eukaryotic cells such as single celled plants, and advanced eukaryotic cells … See more • Background radiation • Linear energy transfer (LET) • Theory of dual radiation action See more For the purposes of computing the equivalent dose to an organ or tissue, the International Commission on Radiological Protection (ICRP) … See more In 1931, Failla and Henshaw reported on determination of the relative biological effectiveness (RBE) of x rays and γ rays. This appears to be the first use of the term ‘RBE’. The authors noted that RBE was dependent on the experimental system being studied. … See more • Relative Biological Effectiveness in Ion Beam Therapy See more Web4 Department of Radiology, Hyogo Ion Beam Medical Center, 1-2-1 Kouto, Shingu-cho, Tatsuno, Hyogo 679 ...

Webrem, unit of radiation dosage (such as from X rays) applied to humans. Derived from the phrase Roentgen equivalent man, the rem is now defined as the dosage in rads that will cause the same amount of biological injury as one rad of X rays or gamma rays. Formerly poorly defined, the rem was redefined in 1962 to clarify the usage of the term relative … WebIn radiology departments, typically we’re primarily concerned about x-rays, but in other disciplines there are also concerns about the relative radiation damage effects for other … WebINIS Repository Search provides online access to one of the world's largest collections on the peaceful uses of nuclear science and technology.
