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.
Quantity of material introduced into the body by inhalation, ingestion, or through the skin.
Industry:Environment
That portion of the dose equivalent received from radioactive material taken into the body.
Industry:Environment
The process of adding or removing one or more electrons from atoms or molecules. High temperatures, electrical discharges, or radiation can cause ionization.
Industry:Environment
An instrument that detects and measures ionizing radiation by measuring the electrical current that flows when radiation ionizes gas in a chamber, making the gas a conductor of electricity.
Industry:Environment
Any radiation capable of displacing electrons from atoms or molecules, producing ions. Examples: alpha, beta, gamma, x-rays, neutrons, and ultraviolet light. High doses may produce severe skin or tissue damage.
Industry:Environment
Exposure to radiation.
Industry:Environment
One of two or more atoms with the same number of protons, but different number of neutrons, in their nuclei. Example: 12C, 13C, and 14C are isotopes of the same element. Isotopes have very nearly the same chemical properties, but often different physical properties (12C and 13C are stable, while 14C is radioactive).
Industry:Environment
The permissible upper bounds of radiation doses.
Industry:Environment
A method of determining activity of a radioactive sample using a liquid Fluor and a means of detecting the scintillation resulting from the interaction of radiation with the Fluor.
Industry:Environment
A detector which combines a scintillation crystal (produces light when struck by ionizing radiation), a photomultiplier tube, and associated electronic circuits for counting light emissions produced in the crystal (NaI) by ionizing radiation. A NaI scintillation probe with a ratemeter can be used for detection of gamma and x-rays.
