Guideline: No restrictions on contact with partner following FDG scan Restrictions on travel by public transport may vary in different countries. It can take 15-26 hrs before 400 MBq of 18F-FDG decays below 37 kBq. Some radiation monitors used for public transport protection are activated at 37 kBq* Children should not accompany patient to PET/CT unit but no restrictions on contact once patient leaves the unit Reduce close contact time with infants during first 12 hours post injection
