The effect of non-ionizing forms of radiation on living tissue has only recently been studied. Nevertheless, different biological effects are observed for different types of non-ionizing radiation. Even "non-ionizing" radiation is capable of causing thermal-ionization if it deposits enough heat to raise temperatures to ionization energies.

Radiation protection, also known as radiological protection, is defined by the International Atomic Energy Agency (IAEA) as "The protection of people from harmful effects of exposure to ionizing radiation, and the means for achieving this". Exposure can be from a source of radiation external to the human body or due to internal irradiation caused by the ingestion of radioactive …

Acute dose · 200 to 300 rad to the skin can result in the reddening of the skin (erythema), similar to a mild sunburn and may result in hair loss ...

In general, ionizing radiation is harmful and potentially lethal to living beings but can have health benefits in radiation therapy for the treatment of cancer and thyrotoxicosis. Most adverse health effects of radiation exposure may be grouped in two general categories:

Ionizing radiation deposits energy in the matter being irradiated. The quantity used to express this is the absorbed dose, a physical dose quantity that is dependent on the level of incident radiation and the absorption properties of the irradiated object.Absorbed dose is a physical quantity, and is not a satisfactory indicator of biological effect, so to allow consideration of the …

Biological damage can lead to cellular death, which can occur over time periods from seconds and up to years. All these processes lead to the final radiobiological effect of the radiation on the human body. Ionizing radiation can, apart from causing damage, also lead to activation of adaptive and protective mechanisms.

There are two different types of damaging biological effects due to ionizing radiation on the cellular level. Exposure can cause either cell ...

Radiation can harm either the whole body (somatic damage) or eggs and sperm (genetic damage). Its effects are more pronounced in cells that reproduce rapidly, ...

Biological Effects of Exposure to Radiation. Radiation can harm either the whole body (somatic damage) or eggs and sperm (genetic damage). Its effects are more pronounced in cells that reproduce rapidly, such as the stomach lining, hair follicles, bone marrow, and embryos.

b) Effects on chromosomes – use in biodosimetry c) Radiobiological definition of cell death and cell survival d) Manifestations of radiation-induced cell ...

Although we tend to think of biological effects in terms of the effect of radiation on living cells, in actuality, ionizing radiation, by definition, ...

Ionizing radiation can cause biological effects which are passed on to offspring through the epigenome. The effects of radiation on cells has been found to be dependent on the dosage of the radiation, the location of the cell in regards to tissue, and whether the cell is a somatic or germ line cell.

The biological effects of ionising radiation are caused by the secondary electrons from an ionisation event, not the primary ...

All the effects of ionizing radiation on biological tissue can be understood by knowing that ... Quantity, SI unit name, Definition, Former unit, Conversion ...

High-energy visible light (HEV light) is high-frequency, high-energy light in the violet/blue band from 400 to 450 nm in the visible spectrum, which has a number of biological effects, including those on the eye.. Despite a lack of any concurring scientific evidence, HEV light has sometimes been claimed to be a cause of age-related macular degeneration.

Some effects of ionizing radiation on human health are stochastic, meaning that their probability of occurrence increases with dose, while the severity is ...
