An alternative to conventional shielding for megavoltage therapy rooms.
Dry silica sand as an "in-wall" shielding medium for megavoltage teletherapy rooms is discussed. Shielding considerations, construction techniques, and survey results are presented for a 6-MV facility using sand shielding for both primary and secondary barriers.
