I completed a construction of Radiation Shielding Concrete (basement and semi-basement) for Oncology treatment ( LINAC, Cyclotron and Cyberknife). I'd like to set guidelines and/or recommendations for future use of the facility.
Construction materials:
Concrete - density is maintained 2.5 gm/cc, slump < 75
CA - 2/3 in and 1/2 in stone chips
Admixture- Masterpolyheed
Cement - PPC
Ice was introduced to reduce hydration temperature
