Shielding Design
Having a proper shielding design is an essential requirement for licensing purposes and for ensuring safety in facilities where ionising radiation sources/equipment are used. To register an ionising radiation source, a shielding plan must be submitted to the regulator before commencing construction. In some jurisdictions, a certificate of compliance for the premises must be completed by a certified radiation expert following the installation of shielding. If any modifications in procedures, workloads, source modality or occupancy of surrounding areas are made at any point in time, a new shielding assessment must be prepared to reflect the minimum shielding requirements that satisfy compliance with regulations.
Undoubtedly, the calculation of radiation doses and corresponding shielding amounts needed to meet specified design goals becomes a sophisticated task in the presence of multiple radiation doses. Consequently, engaging a qualified Health Physicist is crucial to navigate these complexities and ensure effective radiation protection measures are in place.
