Radiosensitivity is the relative susceptibility of cells, tissues, organs or organisms to the harmful effect of ionizing radiation. Cells types affected Cells ...
The human body contains many types of cells and a human can be killed by the loss of a single tissue in a vital organ [citation needed]. For many short term radiation deaths (3 days to 30 days) the loss of cells forming blood cells ( bone marrow ) and the cells in the digestive system (wall of the intestines ) cause death.
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.
This figure illustrates the typical change in the relative radiosensitivity for a biological effect such as cell death when exposed to radiations of low ionizing density (e.g. x-rays). The hyperbolic relationship shown has a maximum OER of 2.70 for 100% oxygen (at 760 mmHg), with a half-range OER value at 4.2 mmHg or 0.55% of oxygen.

Effective dose is a dose quantity in the International Commission on Radiological Protection (ICRP) system of radiological protection. [1]It is the tissue-weighted sum of the equivalent doses in all specified tissues and organs of the human body and represents the stochastic health risk to the whole body, which is the probability of cancer induction and genetic effects, of low levels of ...
