Peak skin dose

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 D_{skin, local} (ICRU, 2005). The notation used by the National Council on Radiation Protection and Measurements is D_skin,max (NCRP, 2010). Peak skin dose is measured in units of Gy (NCRP, 2010).
