Optimizing Radiation Safety Issues :
Post Injection Waiting Room: Barriers, partitions and shielding should be designed to protect operations personnel, other equipment and public areas from sources of radioactivity.
Site Measurements: If other scanners are located close by, high energy photons may interfere with other scans. Therefore, injected patients should remain 5-6 meters from other scanning equipment to minimize scanner interference. A shielded area may be necessary for the scanner and patient holding areas for F-18 uptake.
Measurements in Adjacent Offices: An assessment of patient waiting areas, injection areas and surrounding public areas should be made to determine if the restricted area designation is still adequate. The current maximum dose rate for an unrestricted area is 2 mR /hr and 100 mR/year (10 CFR 20:1301)
Technologist Control Room: It is recommended that at least 1/4" to 2 inches of lead are necessary for shielding these areas.
Shielding of PET Waiting Room: It is recommended that at least 1/4" to 2 inches of lead are necessary for shielding these areas.
