scope:

Report 60 provides definitions for fundamental quantities employed in (1) radiometry, (2) specification of interaction coefficients, (3) dosimetry and (4) radioactivity. In addition to scalar quantities, the new Report also treats relevant vectorial quantities. A definition of cema is provided, a quantity for assessing energy lost by charged particles in a way analogous to the use of kerma for assessing the transfer of energy by uncharged particles. Tables in the Report provide succinct, mathematical definitions of quantities, as well as symbols and units for each quantity. The major sections of ICRU Report 60 are:

• General Consideration

• Radiometry I

• Interaction Coefficients and Related Quantities

• Dosimetry

• Radioactivity
