Radiosensitivity is the relative susceptibility of cells, tissues, organs or organisms to the harmful effect of ionizing radiation. Cells types affected [ edit ]
Radiation weighting factors are largely based on the RBE of radiation for stochastic health risks. However, for simplicity, the radiation weighting factors are not dependent on the type of tissue, and the values are conservatively chosen to be greater than the bulk of experimental values observed for the most sensitive cell types, with respect ...
Another important observation is that oxygen must be present at irradiation or within milliseconds afterward for the oxygen effect to take place. [ 8 ] The best known explanation of the oxygen effect is the oxygen fixation hypothesis developed by Alexander in 1962, [ 9 ] which posited that radiation-induced non-restorable or "fixed" nuclear DNA ...
Conventional chemotherapeutics are currently being used in conjunction with radiation therapy to increase its effectiveness. Examples include the fluoropyrimidines, gemcitabine and platinum analogs; fluoropyrimidines increase sensitivity by dysregulating S-phase cell cycle checkpoints in tumor cells.
Radiation sensitivity is the susceptibility of a material to physical or chemical changes induced by radiation. [1] Examples of radiation sensitive materials are silver chloride, photoresists and biomaterials.
"For people wanting to act on this information, I suggest they talk to their health care providers about what steps they may want to take to help prevent and screen for cancer." The study had some ...
The two women fled the residence to await authorities. Demskiy refused to answer the door for responding sheriff’s deputies. They “forced entry” into the home upon learning the tot was still ...
The committed dose is a measure of the stochastic health risk due to an intake of radioactive material into the human body. The ICRP states "For internal exposure, committed effective doses are generally determined from an assessment of the intakes of radionuclides from bioassay measurements or other quantities.
