Carlo Fidani Peel Regional Cancer Center at the Credit Valley Site of the Credit Valley Hospital and Trillium Health Center is currently undergoing a redevelopment to build a brachytherapy suite and associated areas with a projected start date of April 2013. The new brachytherapy suite will be located in the PRCC, and is a redevelopment of office area into clinical space. The workload for the full brachytherapy program is expected to be 20 patients per week, in cervix, prostate, skin, lung and other sites. There were challenges for shielding due services in the slab to the renal clinic located above the redevelopment area. The presence of over 30 voids in the slab and upper walls made the solution to add shielding to the underside of the current slab unsuitable. To overcome this, a second ceiling built below the slab to allow for an uninterrupted shielding for the brachytherapy suite. The additional ceiling allows for a crawl space between slab and shielding allowing for servicing if needed for the drains from the renal clinic. The appropriate finalized shielding design is 69mm of lead brick supported by steel plate and steel beams. Final shielding for the walls is 690mm of concrete that allows public access to all hallways around the facility. The final design for the new brachytherapy site at the PRCC all services for the room are located within the shielding and all services for areas outside the room are located outside the shielding.
