Jump to navigation Jump to search

The maximum absorbed dose to the most heavily exposed localised region of skin (i.e. the localised region of skin that lies within the primary x-ray beam for the longest period of time or multiple exposures during a fluoroscopically guided procedure). The notation used by the International Commission on Radiation Units and Measurements for this quantity is Dskin, local (ICRU, 2005). The notation used by the National Council on Radiation Protection and Measurements is Dskin,max (NCRP, 2010). Peak skin dose is measured in units of Gy (NCRP, 2010).
