   Bob- When you see the plans, you'll know. That stuff is highly regulated, and should come with detailed drawings. My guess is sheet lead sandwiched in two sheets of plywood, or sheet lead sheathing behind the drywall. Doors are probably site built the same way. Let us know what comes up, this is interesting stuff.

   *Hmm, here i was going to make a silly joke, and it turns out you ARE talking about "real" radiation. As JR suggests, the site design should be quite specific, and i'm sure the mfgr spells out what they need. CT actually uses very little radiation, and what radiation does spread beyond the apparatus diminishes in intensity with the square of the distance, so not much shielding is needed. Techs do portable chest X-rays in patient rooms without any special precautions other than distance.(In high school i volunteered at a hospital where i transported patients to a mobile unit housed in a semi trailer. This was in the days when hospitals had to share the devices.)Sounds like an interesting project.P.S. Don't call it "CAT scan." That's dated to when "computed tomography" was done only "axially" -- maybe 20 years ago.

   Andrew,
   Appreciate your input. As yet, the specs do not fully detail the requirements - final specs are due out at the end of this week.

   By the way, the hospital fundraising campaign for this equipment is entitled "Bring in the CAT"!!

   I am about to bid on a CAT scan room in a hospital. I understand that there may be a laminated plywood with a lead core. Anyone run into this or any other suggestions for shielding the radiation
