Herbert Parker (health Physicist)
Herbert M. Parker (13 April 1910, Accrington – 5 March 1984, Richland, Washington) was an English, and American immigrant, medical physicist. He was a pioneer of medical radiation therapy and radiation safety, known for introducing the roentgen equivalent physical (rep), the forerunner of the gray and the rad, and also the roentgen equivalent biological (reb), the forerunner of the rem and the sievert. Career After receiving an M.S. in physics from the University of Manchester in 1931, Parker became a medical physicist at the Christie Hospital and the Holt Radium Institute in Manchester. With James R. Paterson, he developed in 1932 the Paterson-Parker method, or Manchester System, for radiation therapy. The method allows physicians to use radium needles or tubes to maximize the radiation dose delivered to a cancerous tumour whilst minimizing the dose to healthy tissue. In 1938 Parker immigrated to the U.S.A. to begin work at the Swedish Hospital in Seattle, where he worked ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Accrington
Accrington is a town in the Hyndburn borough of Lancashire, England. It lies about east of Blackburn, west of Burnley, east of Preston, north of Manchester and is situated on the culverted River Hyndburn. Commonly abbreviated by locals to "Accy", the town has a population of 35,456 according to the 2011 census. Accrington is a former centre of the cotton and textile machinery industries. The town is famed for manufacturing the hardest and densest building bricks in the world, "The Accrington NORI" (iron), which were used in the construction of the Empire State Building and for the foundations of Blackpool Tower; famous for Accrington Stanley F.C. and the Haworth Art Gallery which holds Europe's largest collection of Tiffany glass. History Origin of the name The name Accrington appears to be Anglo-Saxon in origin. The earliest citing appears in the Parish of Whalley records of 850; where it is written ''Akeringastun''. In later records, the name variously appears as ''Ak ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
General Electric Corporation
General Electric Company (GE) is an American Multinational corporation, multinational Conglomerate (company), conglomerate founded in 1892, and incorporated in New York (state), New York state and headquartered in Boston. The company operated in sectors including GE Healthcare, healthcare, GE Aviation, aviation, GE Power, power, GE Renewable Energy, renewable energy, GE Digital, digital industry, additive manufacturing and GE Capital, venture capital and finance, but has since divested from several areas, now primarily consisting of the first four segments. In 2020, GE ranked among the Fortune 500 as the 33rd largest firm in the United States by gross revenue. In 2011, GE ranked among the Fortune 20 as the 14th most profitable company, but later very severely underperformed the market (by about 75%) as its profitability collapsed. Two employees of GE – Irving Langmuir (1932) and Ivar Giaever (1973) – have been awarded the Nobel Prize. On November 9, 2021, the company anno ...

Medical Physicists
Medicine is the science and practice of caring for a patient, managing the diagnosis, prognosis, prevention, treatment, palliation of their injury or disease, and promoting their health. Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness. Contemporary medicine applies biomedical sciences, biomedical research, genetics, and medical technology to diagnose, treat, and prevent injury and disease, typically through pharmaceuticals or surgery, but also through therapies as diverse as psychotherapy, external splints and traction, medical devices, biologics, and ionizing radiation, amongst others. Medicine has been practiced since prehistoric times, and for most of this time it was an art (an area of skill and knowledge), frequently having connections to the religious and philosophical beliefs of local culture. For example, a medicine man would apply herbs and say prayers for healing, or an ancie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Health Physics Society
The Health Physics Society (HPS) is a nonprofit scientific professional organization whose mission is excellence in the science and practice of radiation safety. It is based in the United States and the specific purposes of the society's activities include encouraging research in radiation science, developing standards, and disseminating radiation safety information. Society members are involved in understanding, evaluating, and controlling potential risks from radiation relative to the benefits. The Society was formed in 1955, with an organizational meeting in June, 1955 at Ohio State University Columbus, Ohio. As of 2013, the membership consists of approximately 5,500 scientists, physicians, engineers, and other professionals. The headquarters are in McLean, VA. The society is an affiliate of the American Institute of Physics. Activities It publishes ''Health Physics'' since 1958, a peer-reviewed scientific journal; ''Health Physics News'' for material of interest to mem ...

Health Physicists
Health, according to the World Health Organization, is "a state of complete physical, mental and social well-being and not merely the absence of disease and infirmity". World Health Organization. (2006)''Constitution of the World Health Organization''– ''Basic Documents'', Forty-fifth edition, Supplement, October 2006. A variety of definitions have been used for different purposes over time. Health can be promoted by encouraging healthful activities, such as regular physical exercise and adequate sleep, and by reducing or avoiding unhealthful activities or situations, such as smoking or excessive stress. Some factors affecting health are due to individual choices, such as whether to engage in a high-risk behavior, while others are due to structural causes, such as whether the society is arranged in a way that makes it easier or harder for people to get necessary healthcare services. Still, other factors are beyond both individual and group choices, such as genetic disord ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manhattan Project People
Manhattan (), known regionally as the City, is the most densely populated and geographically smallest of the five boroughs of New York City.

Alumni Of The University Of Manchester
Alumni (singular: alumnus (masculine) or alumna (feminine)) are former students of a school, college, or university who have either attended or graduated in some fashion from the institution. The feminine plural alumnae is sometimes used for groups of women. The word is Latin and means "one who is being (or has been) nourished". The term is not synonymous with "graduate"; one can be an alumnus without graduating ( Burt Reynolds, alumnus but not graduate of Florida State, is an example). The term is sometimes used to refer to a former employee or member of an organization, contributor, or inmate. Etymology The Latin noun ''alumnus'' means "foster son" or "pupil". It is derived from PIE ''*h₂el-'' (grow, nourish), and it is a variant of the Latin verb ''alere'' "to nourish".Merriam-Webster: alumnus .. Separate, but from the ...

1910 Births
Year 191 ( CXCI) was a common year starting on Friday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Apronianus and Bradua (or, less frequently, year 944 ''Ab urbe condita'').

American Radium Society
The American Radium Society is a medical association devoted to the study and treatment of cancer. It was founded in 1916. The Society's original mission was to further "the scientific study of radium in relation to its physical properties and therapeutic applications" distinguishing it from the American Roentgen Ray Society (ARRS). The society's mission was expanded in 1950 to include "the treatment of neoplastic and allied diseases and the study and application of ionizing radiation."Johnstone, Peter (April 2013)"A Brief History of the American Radium Society" '' American College of Radiology Bulletin'', p. 19 In the ensuing years its focus became increasingly multidisciplinary. In 1933, The ARS founded the annual Janeway Lecture in honor of Henry Harrington Janeway, a pioneer in radium therapy. The first Janeway Lecture, "Early Experience in Radium Therapy", was given by the pathologist James Ewing. The lecture is delivered at the society's annual general meeting with the lec ...
