The Integrated Risk Information System (IRIS) is an environmental assessment program operated by the U.S. Environmental Protection Agency (EPA). The IRIS program is focused on risk assessment , and not risk management (those decision processes involving analysis of regulatory, legal, social and economic considerations related to the risks being ...
The Environmental Protection Agency (EPA) is an independent agency of the United States government tasked with environmental protection matters. [2] President Richard Nixon proposed the establishment of EPA on July 9, 1970; it began operation on December 2, 1970, after Nixon signed an executive order. [3]
A year after Röntgen's discovery of X-rays in 1895, the American engineer Wolfram Fuchs gave what was probably the first radiation protection advice, but many early users of X-rays were initially unaware of the hazards and protection was rudimentary or non-existent. [11] The dangers of radioactivity and radiation were not immediately recognized.
Radiation exposure can be managed by a combination of these factors: Time: Reducing the time of an exposure reduces the effective dose proportionally. An example of reducing radiation doses by reducing the time of exposures might be improving operator training to reduce the time they take to handle a radioactive source.
The Environmental Protection Agency (EPA) works with state and local governments throughout the United States to control and abate environmental pollution and to address problems related to solid waste, pesticides, radiation, and toxic substances. The EPA sets and enforces standards for air, soil and water quality, evaluates the impact of ...
After revelations that radioactive waste may be buried under two Bay Area parks, the cities of Albany and Berkeley submitted testing plans. Albany's was approved; Berkeley's was deemed insufficient.
Radiation is a moving form of energy, classified into ionizing and non-ionizing type. [4] Ionizing radiation is further categorized into electromagnetic radiation (without matter) and particulate radiation (with matter). [4] Electromagnetic radiation consists of photons, which can be thought of as energy packets, traveling in the form of a wave ...
Electromagnetic radiation from the corona, seen as light during an eclipse, is perfectly safe, but there is another form of radiation that travels to Earth from the sun—neutrinos.
