If hospitals are constantly fearful that wireless handsets will disrupt all that sensitive electrical and radiological equipment used all over most current hospitals, some (or all) of that fear can be put to rest for now, even if that beloved handset is dirtier than a hospital toilet. A new study concluded that wireless phone calls do not affect hospital medical devices. On the flip side of the RF dial, though, the same study said that anti-theft alarm devices used in many retail stores could accidentally trigger misfires in implanted heart devices. So, if you enter a retailer and have a heart murmur as a result, at least you'll be able to call relatives from the ER waiting room without disrupting all that hospital equipment around you and everyone else.
