In … WitrynaEffects of radiation may also be heritable, affecting the progeny or children of those with exposure during pregnancy. Ionizing radiation may affect different organ systems in the body and, depending on the dose, health effects may manifest from skin reddening with small doses to sterility and even death with large doses.
Witryna20 sie 2024 · The present system of radiation protection assumes that exposure at low doses and/or low dose-rates leads to health risks linearly related to the dose. They are evaluated by a combination of epidemiological data and radiobiological models. The latter imply that radiation induces deleterious effects via genetic mutation caused by DNA … Witryna12 sty 2015 · Heritable effects (genetic effects) Mutations result from any sudden change to a gene or chromosome. They can be caused by external factors, such as radiation or may occur spontaneously. Radiation to the reproductive organs may damage the DNA of the sperm or egg cells.
