William Herbert Rollins (June 19, 1852 - 1929) was an American scientist, inventor, and dentist. He was a pioneer in radiation protection.Many of his inventions and investigations in medical radiography and photography have been ranked in importance with those of Thomas A. Edison, Elihu Thomson, and William J. Morton.
Health Physics is a monthly peer-reviewed medical journal published by Lippincott Williams & Wilkins. Its scope includes research into radiation safety and healthcare applications. It is the official journal of the Health Physics Society. It was established in 1958 and it is edited by Brant Ulsh.
Health physicists principally work at facilities where radionuclides or other sources of ionizing radiation (such as X-ray generators) are used or produced; these include research, industry, education, medical facilities, nuclear power, military, environmental protection, enforcement of government regulations, and decontamination and ...
If good health physics controls are maintained in a laboratory where radionuclides are used, it is unlikely that the overall radiation dose received by workers will be of much significance. Nevertheless, the effects of low doses are mostly unknown so many regulations exist to avoid unnecessary risks, such as skin or internal exposure.
Caldwell was born in Savannah, Missouri, to attorney William W. Caldwell and the former Camilla Kellogg. [1] [2] He showed an early interest in mechanical and electrical devices, having grown up in an era during which a number of electrical innovations had been significantly refined, including the electric light, telephones, and transatlantic telegraph cables.
Kerala's monazite sand (containing a third of the world's economically recoverable reserves of radioactive thorium) emits about 8 microsieverts per hour of gamma radiation, 80 times the dose rate equivalent in London, but a decade-long study of 69,985 residents published in Health Physics in 2009 "showed no excess cancer risk from exposure to ...
Elizabeth Fleischman, American X-ray pioneer (1899) Elizabeth Fleischman-Aschheim ( née Fleischman 5 March 1867 – August 3 1905) was an American radiographer who is considered an X-ray pioneer. Fleischman was the first woman to die as a result of X-ray radiation exposure.
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.
