Actually, there is nothing wrong with this picture. It’s an issue of proximity. Most hospitals are filled with areas that are remarkably well shielded from the outside world. That is to say, the walls, ceiling and floors are more than the standard issue materials. In addition to the MRI areas, other areas are well shielded. So, having three cell towers on the property is almost meaningless. Almost.
Having one person, with by awful luck the matching frequency to a pacemaker, WALKING BY a room in the CICU ward, is much more likely. As mentioned above, cellular phones are passively transmitting devices. They are ALWAYS transmitting, and always recieving. They catch voicemail reminders within seconds of the mail being left. They relay roaming and tower signal and switch data incessantly. They are truly always generating information. Therein lays the danger.
And, for those posters who have seen Doctors using cellular phones in areas where they are banned? Drop the dime and call OSHA, or the state DOH. They either obey the rules like everyone else, or saw their bones elsewhere. The whole M-Diety thing makes me gag.
