Abstract
A unit is necessary for the measurement of any physical quantity. The International Commission on Radiation Units and Measurement (ICRU) reviews and updates, from time to time, the concepts related to quantities and their units in radiation physics, dosimetry and radiological protection.
Some of the quantities of interest are activity, air Kerma, exposure, absorbed dose, effective dose, equivalent dose, collective equivalent dose, annual limit of intake and derived air concentration. In 1980, the ICRU recommended SI units for the above quantities. These new units along with the corresponding old units are discussed in the following paragraphs.
