IT has been known for some time 1,2 that the presence of aromatic compounds in solutions of saturated hydrocarbons can protect the solvent against radiation-induced decomposition. Rather, it has been proposed 2 that some sort of efficient energy transfer from the solvent, which absorbs the primary radiation, to the solute must operate. The recent observations of thermal electrons produced in relatively high yield in the radiolysis of aliphatic hydrocarbons in the glassy 6 and liquid 7 states indicated that it would be interesting to investigate whether there is a link between radiation protection by aromatic compounds and their electron affinity as it is known that these compounds are electron acceptors.

Absolute risk: the proportion of a population expected to get a disease over a specified time period. See also risk , relative risk. Absorbed dose: Animation the amount of energy deposited by ionizing radiation in a unit mass of tissue. Actinides: elements in the periodic table with atomic numbers from 90 to thorium to lawrencium ; i. These are also called "rare earth metals. Actinides with atomic numbers higher than 92 do not occur naturally but are produced artificially by bombarding other elements with particles. Some of the actinides include plutonium, curium, and californium.

While everyone is exposed to natural background radiation , workers may also be exposed to ionizing radiation in workplaces with radiation sources. These radiation sources can pose a health risk to workers if not properly controlled. Occupational settings with ionizing radiation sources include:. This Ionizing Radiation Safety and Health Topics page provides a starting point for technical and regulatory information regarding the recognition, evaluation, and control of occupational health hazards associated with ionizing radiation. The radiation protection guidance discussed here should be implemented within a framework of existing OSHA standards, including, as applicable, those for ionizing radiation and personal protective equipment PPE. This webpage discusses such standards generally and collectively.

Radiation plays a key role in modern life, be it the use of nuclear medicine, space exploration or electricity generation. Radiation constantly surrounds us as a result of naturally occurring radioactive elements in e. As a result of many decades of research, the health impacts of radiation are very well-understood. The sources of radiation causing the greatest exposure of the general public are not necessarily those that attract the most attention. At its most fundamental level, radioactivity is a question of energy, and the desire for unstable elements to become stable.

Units of radiation and radioactivity

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". Ionizing radiation is widely used in industry and medicine, and can present a significant health hazard by causing microscopic damage to living tissue. There are two main categories of ionizing radiation health effects. At high exposures, it can cause "tissue" effects, also called "deterministic" effects due to the certainty of them happening, conventionally indicated by the unit gray and resulting in acute radiation syndrome. For low level exposures there can be statistically elevated risks of radiation-induced cancer , called " stochastic effects" due to the uncertainty of them happening, conventionally indicated by the unit sievert.
