Local Rules

Local Rules are a requirement of the UK Ionising Radiations Regulations 2017 (IRR17) , particularly where you one or more designated areas (Controlled Area or Supervised Areas). Local Rules are the written instructions in order to comply with IRR17 and work safely with ionising radiation. They are closely related to the Radiation Protection Supervisor (RPS) who is a person appointed under IRR17 to ensure the Local Rules are implemented. They will detail RPS contact details, a description of the designated area, the dose investigation level, details of dosimetry or monitoring requirements and other written arrangements to restrict exposure (i.e. ALARP).
