Detector is a device that is sensitive to radiation and can produce a response signal suitable for measurement or analysis. A radiation detection instrument.
Collective dose (Animation) The sum of the individual doses received in a given time period by a specified population from exposure to a specified source of radiation
Biodosimetry The use of physiological, chemical or biological markers of exposure of human tissues to ionizing radiation for the purpose of reconstructing doses to individuals or populations.
Electron volt (eV) is a unit of energy equivalent to the amount of energy gained by an electron when it passes from a point of low potential to a point one volt higher in potential
Decay constant is the fraction of a number of atoms of a radionuclide that disintegrates in a unit of time. The decay constant is inversely proportional to the radioactive half-life.
Assigned Protection Factor Assigned Protection Factor (APF) means the workplace level of respiratory protection that a respirator or class of respirators is expected to provide to employees enrolled in a continuing, effective respiratory protection program.
Epidemiology is the study of the distribution and determinants of health-related states or events in specified populations; and the application of this study to the control of health problems.
Background radiation ionizing radiation from natural sources, such as terrestrial radiation due to radionuclides in the soil or cosmic radiation originating in outer space.
Committed dose a dose that accounts for continuing exposures expected to be received over a long period of time (such as 30, 50, or 70 years) from radioactive materials that were deposited inside the body. For more information
