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 ...
Supervisors at EPA's National Center for Environmental Assessment required several paragraphs to be deleted from a peer-reviewed journal article about EPA's integrated risk information system, which led two co-authors to have their names removed from the publication, and the corresponding author, Ching-Hung Hsu, to leave EPA "because of the ...
The Advisory Committee on X-Ray and Radium Protection was established in 1929. [1] Initially, the organization was an informal collective of scientists seeking to proffer accurate information and appropriate recommendations for radiation protection.
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 Total effective dose equivalent (TEDE) is a radiation dosimetry quantity defined by the US Nuclear Regulatory Commission to monitor and control human exposure to ionizing radiation. It is defined differently in the NRC regulations and NRC glossary.
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 ...
CBRN disposal technicians taking part in a training exercise. Chemical, biological, radiological, and nuclear defense (CBRN defense) or Nuclear, biological, and chemical protection (NBC protection) is a class of protective measures taken in situations where chemical, biological, radiological, or nuclear (including terrorism) hazards may be present.
