| dose |
A (total or accumulated) quantity of ionizing (or nuclear) radiation. The absorbed dose in rads represents the amount of energy absorbed from the radiation per gram of specified absorbing material. (From The Effects of Nuclear Weapons, Third Edition, Samuel Glasstone and Philip J. Dolan, US Department Defense and Department of Energy, 1977).

| dose rate |
As a general rule, the amount of ionizing (or nuclear) radiation which an individual or material would receive per unit of time. It is usually expressed as rads (or rems) per hour or in submultiples of these units, such as millirads per hour. (From The Effects of Nuclear Weapons, Third Edition, Samuel Glasstone and Philip J. Dolan, US Department Defense and Department of Energy, 1977).

| dose |
A percentage of the maximum allowable noise that a worker can be exposed to per day. This is a computation that is based on the following variables: criterion level, lower threshold and exchange rate. Dose is expressed as a percentage.

| dose |
a measure of the amount of exposure of a living organism to ionizing radiation that takes into account the greater biological harm of alpha radiation; measured in various units, most commonly measured in millirems per exposure episode or per unit of time (see millirem)

| dose equivalent |
The dose equivalent concept allows the scaling up of the absorbed dose in order to better compare the effect of different types of radiation on human systems. Dose equivalent (DE) is expressed in rem (roentgen equivalent man) and is defined as the product of absorbed dose (D) in rads and other necessary modifying factors. In normal protection work the product of absorbed dose and quality factor (QF) expresses the irradiation in terms of a common scale for all ionizing radiations. ...
