Shielding commissioning factors in nuclear medicine facilities.

Abstract

This article reviews the essential considerations in planning and designing nuclear medicine departments. There are four proposed categories to consider as 'shielding commissioning factors' (SCF). The first SCF: 'Patient flow optimisation and workload' emphasises the importance of carefully considering patient flow in the departmental design, which would impact the cost of the shielding and the management of radioactive patients. The second SCF: 'Equipment and space allocation' discusses the principles of space allocations in the department for cost-effective designs. The third SCF: 'Shielding calculation methods' reviews the methodologies of shielding calculations in nuclear medicine to offer a standardised approach. The fourth SCF: 'Shielding integrity' reviews the plan to inspect, eyewitness and verify shielding integrity. All discussions were supplemented by practical examples. Overall, this article aims to be a practical manual which health or medical physicists can use when providing counsels to the design committee.
