International Radiation Protection Association
The International Radiation Protection Association (IRPA) is an independent non-profit association of national and regional radiation protection societies, and its mission is to advance radiation protection throughout the world. It is the international professional association for radiation protection.) IRPA is recognized by the IAEA as a Non Governmental Organization (NGO) and is an observer on the IAEA Radiation Safety Standards Committee (RASSC). IRPA was formed on June 19, 1965, at a meeting in Los Angeles; stimulated by the desire of radiation protection professionals to have a world-wide body. Membership includes 50 Associate Societies covering 65 countries, totaling approximately 18,000 individual members. Structure The General Assembly, made up of representatives from the Associate Societies, is the representative body of the Association. It delegates authority to the Executive Council for the efficient administration of the affairs of the Association. Specific duti ...

Radiation Protection
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". Exposure can be from a source of radiation external to the human body or due to internal irradiation caused by the ingestion of radioactive contamination. 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 (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 ha ...

Ionizing Radiation
Ionizing (ionising) radiation, including Radioactive decay, nuclear radiation, consists of subatomic particles or electromagnetic waves that have enough energy per individual photon or particle to ionization, ionize atoms or molecules by detaching electrons from them. Some particles can travel up to 99% of the speed of light, and the electromagnetic waves are on the high-energy portion of the electromagnetic spectrum. Gamma rays, X-rays, and the higher energy vacuum ultraviolet, ultraviolet part of the electromagnetic spectrum are ionizing radiation; whereas the lower energy ultraviolet, visible light, infrared, microwaves, and radio waves are non-ionizing radiation. Nearly all types of laser light are non-ionizing radiation. The boundary between ionizing and non-ionizing radiation in the ultraviolet area cannot be sharply defined, as different molecules and atoms ionize at Ionization energies of the elements (data page), different energies. The energy of ionizing radiation starts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Radioactivity
Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered ''radioactive''. Three of the most common types of decay are Alpha decay, alpha, Beta decay, beta, and Gamma ray, gamma decay. The weak force is the Fundamental interactions, mechanism that is responsible for beta decay, while the other two are governed by the electromagnetic force, electromagnetic and nuclear forces. Radioactive decay is a randomness, random process at the level of single atoms. According to quantum mechanics, quantum theory, it is impossible to predict when a particular atom will decay, regardless of how long the atom has existed. However, for a significant number of identical atoms, the overall decay rate can be expressed as a decay constant or as a half-life. The half-lives of radioactive atoms have a huge range: f ...

Richard Doll
Sir William Richard Shaboe Doll (28 October 1912 – 24 July 2005) was a British physician who became an epidemiologist in the mid-20th century and made important contributions to that discipline. He was a pioneer in research linking smoking to health problems. With Ernst Wynder, Bradford Hill and Evarts Graham, he was credited with being the first to prove that smoking increased the risk of :lung cancer and :heart disease. (German studies had suggested a link as early as the 1920s but were forgotten or ignored until the 1990s.) He also carried out pioneering work on the relationship between radiation and leukaemia as well as that between asbestos and lung cancer, and alcohol and breast cancer. He however, initially for many years, stood in opposition to research done by Alice Stewart which connected radiation exposure of pregnant mothers to development of leukaemia in their children due to her 'questionable' analysis. On 28 June 2012, he was the subject of an episode of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Lauriston S
Lauriston ( ) is an area of central Edinburgh, Scotland, and home to a number of significant historic buildings. It lies south of Edinburgh Castle and the Grassmarket, and north of The Meadows public park. Lauriston is the former location of the Edinburgh Royal Infirmary, which moved to the area in 1879 in search of fresher air at the edge of the city. Rather than build entirely new facilities, the Infirmary incorporated George Watson's Hospital into the new David Bryce-designed complex. The Infirmary operated as a voluntary hospital and teaching hospital for the University of Edinburgh Medical School until 2003, when operations were moved and the buildings sold to a private developer. The complex underwent major renovations to a design by architects Foster and Partners, resulting in the £750 million mixed-use development branded as the Quartermile. As of 2021, the University of Edinburgh is investing £120 million to convert the remaining main Infirmary buildings to ho ...

William Valentine Mayneord
William Valentine Mayneord, CBE FRS (14 February 1902 – 10 August 1988) was a British physicist and pioneer in the field of medical physics. Early life and education He was born in Redditch, Worcestershire to Walter and Elizabeth Mayneord but after the early death of his mother was adopted by an aunt in Evesham. He was educated at Prince Henry's School, Evesham and gained a Bachelor of Science at the University of Birmingham Career He entered the field of medical physics in 1924 at St Bart's Hospital in London. In 1927 he moved to the Cancer Hospital, now the Royal Marsden Hospital. There he was involved in pioneering work with Izrael Hieger. During World War II he was seconded by the government to work in Canada on the radiological aspects of atomic energy development. It has been said that such was his renown, especially for bringing in the use of the radiological unit the rad, that the SI unit may well have been called the mayneord instead of the gray (2).
