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.
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 ...
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.
On December 16, 1970, the first Administrator of the EPA, William Ruckelshaus, declared that the agency had "a broad responsibility for research, standard-setting, monitoring and enforcement with regard to five environmental hazards; air and water pollution, solid waste disposal, radiation, and pesticides." [12]
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 MDA established a risk-based framework for the classification of medical devices and a regulatory pathway for medical devices to get to the market, created a regulatory pathway for medical device clinical trials, and established several post-market requirements including manufacturer registration and device listing with the FDA, good ...
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.
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 ...
