Abstract:Purpose:
In Ontario, shielding for all X‐ray machines, including CT scanners, must be evaluated according to Safety Code 20A (Health Canada, 1983) which is based on NCRP‐49 (NCRP, 1976).
NCRP‐147 (NCRP, 2004) is the international standard for shielding calculations of CT scanners and is also referenced in Safety Code 35 (Health Canada, 2008) which, was published to supersede SC20A. The goal of this work is to demonstrate the cost effectiveness of NCRP‐147 for CT scanner shielding.
