Abstract :
Electromagnetic interferences (EMI) by cellular phones and PHS terminals were examined in 366 current electric medical equipment (EME) at EMC test sites and 108 units in hospitals. Cellular phones caused EMI in 66% of EME and PHS terminals caused only 8% of EME. The maximum EMI distance was 400 cm in cellular phones and 65 cm in PHS terminals. The levels of interference were also categorized into six grades from the view point of clinical risks. These experimental results suggested the user´s rule of cellular phones and PHS terminals in medical facilities
