This comes to the rescue of my girlfriend who works at a hospital as a Communications Director. She is constantly being given dirty looks when her phone rings.Officially, she’s usually in hallways and not in any of the care areas but the angry looks abound and even though she’s been told its ok for her to use them in the common areas people occasionally tell her off for using it.”Thats dangerous” it “could interfere with the equipment” she’s been told.Well thats not true.In this months Mayo Clinic Proceedings – The authors conducted a 5 month review of the affects of cellular phones on 192 medical devices by conducting 300-odd tests. Nothing went wrong. The same issue of the magazine found that there have been cases of ‘electromagnetic’ interference. Mostly with CD players, but cell phones are considered fine.
