"Still unresolved, the scientists say, is how to stop the screeching noise
that hearing-aid wearers experience when they try to use a cellphone.
Researchers also are trying to understand how a new technology widely used
to track inventory in retail stores might cause problems for people with
pacemakers.
"Most consumer technologies, like televisions and microwaves, don't appear
to interact with medical devices, says Howard Bassen, head of the FDA's
electromagnetics and wireless laboratory.
My comment:
(a) The summary is in the graphic.
(b) Cellphones do not interphere with a pacemaker. Each car of subways and
trains in Japan prominently displays a poster asking people not to use
cellphone near reserved seating for seniors or the handicapped. I have not
seen such sign in US. Armed with the FDA findings, I must say the measures
in Japan are unnecessary. |
