Substantial radiation dose level

An appropriately selected reference value used to trigger additional dose management actions during a procedure and medical follow-up for a radiation level that might produce a clinically relevant injury in an average patient. There is no implication that radiation levels above the SRDL will always cause an injury, or that radiation levels below the SRDL will never cause an injury (NCRP, 2010). (ICRP Publication 120, 2012)
