Lauriston S. Taylor
Lauriston S. Taylor (1 June 1902 – 26 November 2004) was an American physicist known for his work in the field of radiation protection and measurement. Career He established standards for X-ray radiation exposure for the first time in the 1920s, which eventually led to a group of government organizations that set the standards over the next 50 years. Taylor remained active in debates about radiation exposure into his 80s, often advocating the viewpoint that small doses of radiation were not important. Accolades He served as president of the Health Physics Society (HPS) from 1958 to 1959. He was a recipient of the Medal of Freedom, and the Presidential Bronze Star (then the highest military award that could be given to a civilian). Vignettes of early radiation workers In 1977 the Food and Drug Administration of the U.S. Department of Health and Human Services initiated a series of 25 recorded interviews with early radiation workers to provide an historical overview of their res ...

Radiobiology
Radiobiology (also known as radiation biology, and uncommonly as actinobiology) is a field of clinical and basic medical sciences that involves the study of the action of ionizing radiation on living things, especially health effects of radiation. Ionizing radiation is generally harmful and potentially lethal to living things but can have health benefits in radiation therapy for the treatment of cancer and thyrotoxicosis. Its most common impact is the induction of cancer with a latent period of years or decades after exposure. High doses can cause visually dramatic radiation burns, and/or rapid fatality through acute radiation syndrome. Controlled doses are used for medical imaging and radiotherapy. Health effects In general, ionizing radiation is harmful and potentially lethal to living beings but can have health benefits in radiation therapy for the treatment of cancer and thyrotoxicosis. Most adverse health effects of radiation exposure may be grouped in two general categori ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Laurence
George Craig Laurence (21 January 1905 – 6 November 1987) was a Canadian nuclear physicist. He was educated at Dalhousie University, and at Cambridge University under Ernest Rutherford. He was appointed as Radium and X-ray physicist to the Canadian National Research Council in 1930. In 1939-40 he attempted to build a graphite-uranium reactor in Ottawa, anticipating Enrico Fermi's work by several months. In 1942 he joined the Anglo-French nuclear research team at the Montreal Laboratory, where he was responsible for recruiting Canadian scientists. The laboratory later transferred to the Chalk River, and built the ZEEP Reactor, the first outside the U.S.A. In 1946-47 he was in the Canadian delegation to the United Nations Atomic Energy Commission. He then returned to Montreal Laboratory and continued to carry out his research from 1950 to 1961. He was then at the Chalk River Laboratory, and was President of the Atomic Energy Control Board from 1961 to 1970. Laurence Court, a ...

Medical Physicist
A medical physicist is a health professional with specialist education and training in the concepts and techniques of applying physics in medicine and competent to practice independently in one or more of the subfields (specialties) of medical physics. A medical physicist plays a fundamental role in applying physics to medicine, but particularly in the diagnosis and treatment of cancer. The scientific and technological progress in medical physics has led to a variety of skills that must be integrated into the role of a medical physicist in order for them to perform their job. The "medical services" provided to patients undergoing diagnostic and therapeutic treatments must, therefore, be the result of different but complementary skills. In general, the medical physicist is responsible for all scientific and technical aspects of imaging, radiation treatment, and radiation safety. It is their occupational role to ensure that medical modalities offered to patients are met with the utmost ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Adjacent to the main hospital is the Children's Hospital at Montefiore, which serves infants, children, teens, and young adults aged 0–21. History The birth of Montefiore Hospital arose from a series of meetings held in early 1884 among representatives of New York City's synagogues, convened by Dr. Henry Pereira Mendes, to honor Sir Moses Montefiore on his forthcoming one-hundredth birthday. Out of these meetings, held in the rooms of Congregation Shearith Israel, the Montefiore Home for Chronic Invalids, now ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Physicist
A physicist is a scientist who specializes in the field of physics, which encompasses the interactions of matter and energy at all length and time scales in the physical universe. Physicists generally are interested in the root or ultimate causes of phenomena, and usually frame their understanding in mathematical terms. Physicists work across a wide range of research fields, spanning all length scales: from sub-atomic and particle physics, through biological physics, to cosmological length scales encompassing the universe as a whole. The field generally includes two types of physicists: experimental physicists who specialize in the observation of natural phenomena and the development and analysis of experiments, and theoretical physicists who specialize in mathematical modeling of physical systems to rationalize, explain and predict natural phenomena. Physicists can apply their knowledge towards solving practical problems or to developing new technologies (also known as applie ...

Chicago Pile 1
Chicago Pile-1 (CP-1) was the world's first artificial nuclear reactor. On 2 December 1942, the first human-made self-sustaining nuclear chain reaction was initiated in CP-1, during an experiment led by Enrico Fermi. The secret development of the reactor was the first major technical achievement for the Manhattan Project, the Allied effort to create atomic bombs during World War II. Developed by the Metallurgical Laboratory at the University of Chicago, CP-1 was built under the west viewing stands of the original Stagg Field. Although the project's civilian and military leaders had misgivings about the possibility of a disastrous runaway reaction, they trusted Fermi's safety calculations and decided they could carry out the experiment in a densely populated area. Fermi described the reactor as "a crude pile of black bricks and wooden timbers". The reactor was assembled in November 1942, by a team that included Fermi, Leo Szilard (who had previously formulated an idea for non ...

Chain Reaction
A chain reaction is a sequence of reactions where a reactive product or by-product causes additional reactions to take place. In a chain reaction, positive feedback leads to a self-amplifying chain of events. Chain reactions are one way that systems which are not in thermodynamic equilibrium can release energy or increase entropy in order to reach a state of higher entropy. For example, a system may not be able to reach a lower energy state by releasing energy into the environment, because it is hindered or prevented in some way from taking the path that will result in the energy release. If a reaction results in a small energy release making way for more energy releases in an expanding chain, then the system will typically collapse explosively until much or all of the stored energy has been released. A macroscopic metaphor for chain reactions is thus a snowball causing a larger snowball until finally an avalanche results ("snowball effect"). This is a result of stored gravitation ...
