The UFGS has a spec for "RF/EMI Shielding," which is similar shielding for MRI equipment, but the focus of the section is more for military applications and not medical. I found one guide spec from one manufacturer (National MRI Shielding), but would like to have one that is more generic for comparison. If someone has a medical-related section they are willing to share, I'd be greatly indebted to you. Thanks. Ron Geren, FCSI, AIA, CCS, CCCA, SCIP www.specsandcodes.com J.

They assess the type and amount of radiation and recommend the shielding required. J.

If so, make it a performance spec and let the contractor figure it out. ;-) Michael Chusid, RA FCSI CCS www.chusid.com www.buildingproduct.guru 818-219-4937 Ronald L.

Most manufacturers do provide full design services, so that is the direction I want the specification to take.

They haven't advanced their designs or product much since the 50's, but they are solid and effective, experts in their field, and also get certified without issue. I just wish their doors were better looking :-)
