Flashcards: Radiation health effects

Nuclear fallout, or simply fallout, is the residual radioactive material propelled into the upper atmosphere following a nuclear blast or a nuclear reaction conducted in an unshielded facility, so called because it "falls out" of the sky after the explosion and the shock wave have passed.

The Biological timeline of radiation poisoning describes the phenomenon where, following a dose of ionizing radiation, a person may have a period of apparent health, lasting for days or weeks, despite a terminal illness.

Radiation therapy or radiotherapy, often abbreviated RT, RTx, or XRT, is therapy using ionizing radiation, generally as part of cancer treatment to control or kill malignant cells.

Acute radiation syndrome (ARS), also known as radiation poisoning, radiation sickness, or radiation toxicity, is a collection of health effects that are present within 24 hours of exposure to high amounts of ionizing radiation.

A blister is a small pocket of lymph within the upper layers of the skin, typically caused by forceful rubbing (friction), burning, freezing, chemical exposure or infection.

Erythema (from the Greek erythros, meaning red) is redness of the skin or mucous membranes, caused by hyperemia (increased blood flow) in superficial capillaries.

Very strong radiation can induce current capable of delivering an electric shock to persons or animals.

Keloid , also keloidal scar,is the formation of a type of scar which, depending on its maturity, is composed mainly of either type III (early) or type I (late) collagen.

In radiobiology, the relative biological effectiveness (often abbreviated as RBE) is the ratio of biological effectiveness of one type of ionizing radiation relative to another, given the same amount of absorbed energy.

Poison Dust is an American documentary film starring Ramsey Clark, Juan Gonzalez, Rosalie Bertell, Helen Caldicott, Michio Kaku and directed by Sue Harris.

Radioactivity can be used in life sciences as a radiolabel to visualise components or target molecules in a biological system.

Since the discovery of ionizing radiation, a number of human radiation experiments have been performed to understand the effects of ionizing radiation and radioactive contamination on the human body, specifically with the element plutonium.

Hair loss, also known as alopecia or baldness, refers to a loss of hair from part of the head or body.

Pulmonary radiation injury is a general term for damage to the lungs which occurs as a result of exposure to ionizing radiation.

Ex-Rad (or Ex-RAD), also known by the code name ON 01210.

Lauriston S. Taylor (1 June 1902 – 26 November 2004) was an American physicist known for his work in the field of radiation protection and measurement.

Operation Plumbbob was a series of nuclear tests conducted between May 28 and October 7, 1957, at the Nevada Test Site, following Project 57, and preceding Project 58/58A.

The health threat from cosmic rays is the danger posed by galactic cosmic rays and solar energetic particles to astronauts on interplanetary missions or any missions that venture through the Van-Allen Belts or outside the Earth's magnetosphere.

The radiation effects from the Fukushima Daiichi nuclear disaster are the observed and predicted effects resulting from the release of radioactive isotopes from the Fukushima Daiichi Nuclear Power Plant after the 2011 Tōhoku earthquake and tsunami.

The committed dose in radiological protection is a measure of the stochastic health risk due to an intake of radioactive material into the human body.
