[[File:Glossary Icon-2.png|100px|frameless|right|link=ICRP Glossary]]
A DRL for an x-ray procedure set in healthcare facilities within part of a country for a defined clinical imaging task based on the 75th percentile value of the distribution of the appropriate DRL quantity in a reasonable number (e.g. 10–20) of x-ray rooms. Local DRLs may be set for procedures for which no national DRL is available or where there is a national value but local equipment or techniques have enabled a greater degree of optimisation to be achieved so that a value less than the corresponding national DRL can be implemented.
