Say some maniacal world leader finally hits the big red button. Or maybe a terrorist takes out the local nuclear reactor. You survive the initial attack, and you're left to endure a world poisoned by nuclear radiation. How's that gonna feel? Measure the dosage When nuclear reactions get going, they spit out particles with enough energy to rip electrons off of atoms or molecules. The altered bonds produce ion pairs that are extremely chemically reactive. This is known as ionizing radiation, and it's where the problems start. There are many types of ionizing radiation. Take your pick from cosmic, alpha, beta, gamma or X- rays, neutrons, or from a handful more. What really matters is how much an organism is exposed to—a concept called absorbed dose. One way to measure absorbed dose is in units of Grays (Gy). Another common unit is the sievert (Sv), which takes the Gy measure and multiples it by the type of radiation to calculate the effective dose in living tissue.

Radiation includes High-energy electromagnetic waves (x-rays, gamma rays) Particles (alpha particles, beta particles, neutrons) Alpha particles are energetic helium nuclei emitted by some radionuclides with high atomic numbers (eg, plutonium, radium, uranium); they cannot penetrate skin beyond a shallow depth (< 0.1 mm). Beta particles are high-energy electrons that are emitted from the nuclei of unstable atoms (eg, cesium-137, iodine-131). These particles can penetrate more deeply into skin (1 to 2 cm) and cause both epithelial and subepithelial damage. Neutrons are electrically neutral particles emitted by a few radionuclides (eg, californium-252) and produced in nuclear fission reactions (eg, in nuclear reactors); their depth of tissue penetration varies from a few millimeters to several tens of centimeters, depending on their energy. They collide with the nuclei of stable atoms, resulting in emission of energetic protons, alpha and beta particles, and gamma radiation. Gamma radiation and x-rays are electromagnetic radiation (ie, photons) of very short wavelength that can penetrate deeply into tissue (many centimeters). While some photons deposit all their energy in the body, other photons of the same energy may only deposit a fraction of their energy and others may pass completely through the body without interacting. Because of these characteristics, alpha and beta particles cause the most damage when the radioactive atoms that emit them are within the body (internal contamination) or, in the case of beta-emitters, directly on the body; only tissue in close proximity to the radionuclide is affected. Gamma rays and x-rays can cause damage distant from their source and are typically responsible for acute radiation syndromes (ARS—see Radiation Exposure and Contamination : Acute radiation syndromes (ARS)).

People are constantly exposed to low levels of naturally occurring radiation called background radiation. Background radiation comes from cosmic radiation and from radioactive elements in the air, water, and ground. Cosmic radiation is concentrated at the poles by the earth’s magnetic field and is attenuated by the atmosphere. Thus, exposure is greater for people living at high latitudes, at high altitudes, or both and during airplane flights. Terrestrial sources of external radiation exposure are primarily due to the presence of radioactive elements with half-lives comparable to the age of the earth (~4.5 billion years). In particular, uranium (238U) and thorium (232Th) along with several dozen of their radioactive progeny and a radioactive isotope of potassium (40K) are present in many rocks and minerals. Small quantities of these radionuclides are in the food, water, and air and thus contribute to internal exposure as these radionuclides are invariably incorporated into the body. The majority of the dose from internally incorporated radionuclides is from radioisotopes of carbon (14C) and potassium (40K), and because these and other elements (stable and radioactive forms) are constantly replenished in the body by ingestion and inhalation, there are approximately 7,000 atoms undergoing radioactive decay each second. Internal exposure from the inhalation of radioactive isotopes of the noble gas radon (222Rn and 220Rn), which are also formed from the Uranium (238U) decay series, accounts for the largest portion (73%) of the US population's average per capita naturally occurring radiation dose. Cosmic radiation accounts for 11%, radioactive elements in the body for 9%, and external terrestrial radiation for 7%. In the US, people receive an average effective dose of about 3 millisieverts (mSv)/yr from natural sources (range ~0.5 to 20 mSv/yr). However, in some parts of the world, people receive > 50 mSv/yr. The doses from natural background radiation are far too low

Key facts Ionizing radiation is a type of energy released by atoms in the form of electromagnetic waves or particles. People are exposed to natural sources of ionizing radiation, such as in soil, water, and vegetation, as well as in human-made sources, such as x-rays and medical devices. Ionizing radiation has many beneficial applications, including uses in medicine, industry, agriculture and research. As the use of ionizing radiation increases, so does the potential for health hazards if not properly used or contained. Acute health effects such as skin burns or acute radiation syndrome can occur when doses of radiation exceed certain levels. Low doses of ionizing radiation can increase the risk of longer term effects such as cancer. Ionizing radiation is a type of energy released by atoms that travels in the form of electromagnetic waves (gamma or X-rays) or particles (neutrons, beta or alpha). The spontaneous disintegration of atoms is called radioactivity, and the excess energy emitted is a form of ionizing radiation. Unstable elements which disintegrate and emit ionizing radiation are called radionuclides. All radionuclides are uniquely identified by the type of radiation they emit, the energy of the radiation, and their half-life. The activity — used as a measure of the amount of a radionuclide present — is expressed in a unit called the becquerel (Bq): one becquerel is one disintegration per second. The half-life is the time required for the activity of a radionuclide to decrease by decay to half of its initial value. The half-life of a radioactive element is the time that it takes for one half of its atoms to disintegrate. This can range from a mere fraction of a second to millions of years (e.g. iodine-131 has a half-life of 8 days while carbon-14 has a half-life of 5730 years). Radiation sources People are exposed to natural radiation sources as well as human-made sources on a daily basis. Natural radiation comes from many sources including more than
