Radiation biology and protection.
To protect themselves, their patients and their coworkers, radiologic technologists should regularly refresh and reinforce their understanding of key radiation biology and protection principles. This article reviews the concepts of radiation physics, human biology and radiation protection strategies, with emphasis on how historical events and developing research affect radiation protection unde...
متن کاملDose and dose-rate effects of ionizing radiation: a discussion in the light of radiological protection.
The biological effects on humans of low-dose and low-dose-rate exposures to ionizing radiation have always been of major interest. The most recent concept as suggested by the International Commission on Radiological Protection (ICRP) is to extrapolate existing epidemiological data at high doses and dose rates down to low doses and low dose rates relevant to radiological protection, using the so...
متن کاملRadiation dose-rate effects, endogenous DNA damage, and signaling resonance.
We previously concluded, from our analysis of the published data of other investigators, that the yield of germ-line and somatic mutations after exposure to ionizing radiation is parabolically related to the logarithm of the dose-rate at which a given dose is administered. Here we show that other data reveal a similarly parabolic relationship for other ionizing radiation-associated phenomena, n...
متن کاملRadiation Dose-Rate and DNA Damage
In their article, Olipitz et al. (2012) examined signs of DNA damage after chronic exposure of C57Bl6 mice to low-level ionizing radiation (3 mGy/day). For 5 weeks, mice were irradiated continuously with 35.5 keV X-rays produced by the decay of iodine-125, yielding an accumulated dose of 105 mGy. The observed effects were compared with those from acute irradiation by X-ray machine at 1,700 mGy/...
