Harvard University is the oldest institution of higher learning in the United States. It was established in 1636 by the Massachusetts legislature and named after its first benefactor, John Harvard. Located in Cambridge, Massachusetts, Harvard University is an Ivy League university.
The dose received by an individual in a restricted area or in the course of employment in which the individual's assigned duties involve exposure to radiation and to radioactive material. This does not include dose received from background radiation, as a patient from medical procedures, from voluntary participation in medical research programs, or as a member of the general public.
Industry:Environment
The determination of the degree of radioactive contamination on individuals using survey meters, or the determination of radiation dosage received by means of dosimetry devices.
Industry:Environment
The rate of disintegration (transformation) or decay of radioactive material. The units of activity are curie (Ci) and the becquerel (Bq).
Industry:Environment
Any state with which the U. S. Nuclear Regulatory Commission has entered into an effective agreement under subsection 274b. of the Atomic Energy Act of 1954, as amended. Under the agreement, the state regulates the use of by-product, source, and small quantities of special nuclear material within said state.
Industry:Environment
Radioactive material dispersed in the air in the form of dusts, fumes, particulates, mists, vapors, or gases.
Industry:Environment
Making every reasonable effort to maintain exposures to ionizing radiation as far below the dose limits as practical, consistent with the purpose for which the licensed activity is undertaken. It takes into account the state of technology, the economics of improvements in relation to state of technology, the economics of improvements in relation to benefits to the public health and safety, societal and socioeconomic considerations, and in relation to utilization of radioactive materials and licensed materials in the public interest.
Industry:Environment
A positively charged particle ejected spontaneously from the nuclei of some radioactive elements. It is identical to a helium nucleus, with a mass number of 4 and a charge of +2.
Industry:Environment
Annual intake of a given radionuclide by "Reference Man" which would result in either a committed effective dose equivalent of 5 rems or a committed dose equivalent of 50 rems to an organ or tissue.
Industry:Environment
The process by which radiation is reduced in intensity when passing through some material. It is the combination of absorption and scattering processes.
Industry:Environment
Radiation from cosmic sources; naturally occurring radioactive materials, including radon and fallout from nuclear weapons tests.
