ID Number		1079
Study Type		Engineering & Physics
Model		900 MHz, 1.5, 1.9 GHz (CW, PDC, PHS) exposure to medical devices and analysis of electromagnetic interference
Details		The Electronic Medical Equipment Study Group of the Electromagnetic Compatibility Conference in Japan performed testing on medical devices (Baba et al, 1998, J. Clinical Engineering 23:122-136) and made recommendations to the Japanese government in a recent document entitled "Guideline on the use and of Radio Communication Equipment: Safeguards for Electronic Medical Equipment". Testing was performed both in the lab and on site at four different hospitals using 800 MHz and 1.5 GHz PDC with phones in test mode transmitting at 0.8 watts, as well with NTT (analogue) 800 MHz phones transmitting at 0.8 watts and PHS phones operating at 1.9 GHz and transmitting at 80 milliwatts. The authors report a number of EMI issues, although the vast majority were labeled as "low risk" and did not represent any form of critical device malfunction. The authors recommend a safe separation distance or restricting the use of mobile phone handsets in sensitive areas of the hospital.
