Our design of this therapy room includes a three-room suite: a lead-lined patient room, an adjoining room with a lead-lined viewing window where family members can spend the night, and an entry area where clinicians can consult and observe the patient. The room was designed with 3/8-inch thick lead bricks in the walls to meet the requirements of the hospital's radiation physicist. Shielding elements also include sheet lead at the floor and ceiling, lead-lined steel doors; and a viewing window with five-inch thick lead glass. Impervious finishes and seamless materials were used on the floors and walls as a part of mandatory regulation so radioactive traces of the substances can be removed.
