the total dose resulting from repeated or continuous exposures of the same portion of the body, or of the whole body, to ionizing radiation. For more information, see “Primer on Radiation Measurement [..]

(Animation) the amount of a radioactive material that will undergo one decay (disintegration) per second. For more information, see “Primer on Radiation Measurement” from CDC.

the measure and analysis of the radiation being emitted from a person’s entire body, detected by a counter external to the body.

an exposure of the body to radiation, in which the entire body, rather than an isolated part, is irradiated by an external source.

A multiplier that is used for converting the equivalent dose to a specific organ or tissue into what is called the "effective dose." The goal of this process was to develop a method for expr [..]
