102Dosimetry — Radiation dosimetry is the measurement and calculation of the absorbed dose in matter and tissue resulting from the exposure to indirect and direct ionizing radiation. It is a scientific subspecialty in the fields of health physics and medical… …
103Sievert — The sievert (symbol: Sv) is the International System of Units (SI) SI derived unit of dose equivalent radiation. It attempts to quantitatively evaluate the biological effects of ionizing radiation as opposed to just the absorbed dose of radiation …
104Roentgen (unit) — This article is about the unit of measurement. For Röntgen radiation, see X ray. For other uses, see Roentgen. The roentgen (R, also röntgen) is a unit of measurement for exposure to ionizing radiation (such as X ray and gamma rays), and is named …
105Rad (unit) — The rad is a unit of absorbed radiation dose. The rad was first proposed in 1918 as that quantity of X rays which when absorbed will cause the destruction of the malignant mammalian cells in question... [1] It was defined in CGS units in 1953 as… …
106Gray (unit) — The gray (symbol: Gy) is the SI unit of absorbed radiation dose of ionizing radiation (for example, X rays), and is defined as the absorption of one joule of ionizing radiation by one kilogram of matter (usually human tissue).[1] Named after the… …
107gray — The SI unit of absorbed dose of ionizing radiation, equivalent to 1 J/kg of tissue; 1 Gy = 100 rad. SYN: griseus. [Louis H. G., British radiologist, 1905–1965] * * * gray or chiefly Brit grey grā n any of a series of neutral colors ranging… …
108Optical dating — is a method of determining how long ago minerals were last exposed to daylight. It is useful to geologists and archaeologists who want to know when such an event occurred. Alternate names sometimes used are optically stimulated luminescence… …
109Crystal oscillator — A miniature 4 MHz quartz crystal enclosed in a hermetically sealed HC 49/US package, used as the resonator in a crystal oscillator. A crystal oscillator is an electronic oscillator circuit that uses the mechanical resonance of a vibrating crystal …
110factor — 1. One of the contributing causes in any action. 2. One of the components that by multiplication makes up a number or expression. 3. SYN: gene. 4. A vitamin or other essential element. 5. An event, characteristic, or other definable entity that …
