Amongst the body cells, the most sensitive are spermatogonia and erythroblasts, epidermal stem cells, gastrointestinal stem cells. [3] The least sensitive are nerve cells and muscle fibers. Very sensitive cells are also oocytes and lymphocytes, although they are resting cells and do not meet the criteria described above. The reasons for their ...
Radiosensitivity- the susceptibility of living cells, tissues, organs or organisms to the effects of ionizing radiation; References This ...
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.
However, since alpha particles cannot traverse the outermost dead layer of human skin, they can do significant damage only if they come from the decay of atoms inside the body. Since the range of an alpha particle is typically about the diameter of a single eukaryotic cell, the precise location of the emitting atom in the tissue cells becomes ...
Microplastics are everywhere—from the ocean to our bloodstream—raising urgent questions about their impact on human health. Here are 5 tips to reduce your exposure.
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.
Johnson pulled into the parking lot of a gas station in Saratoga Springs and officers found the body of 30-year-old Summer Roney in the back seat, Sgt. Greg Shaver told the outlets.
The U.S. Federal Reserve is expected to reduce its benchmark policy rate by a quarter of a percentage point at the end of its policy meeting on Thursday, a decision that may seem a footnote given ...
