[Greenbuilding] Smoke detectors and EMF

[Irina Golfman]

Hello everyone,

I am trying to figure out if the hard wired or battery operated 
photo-electric smoke detectors will produce a smaller 
Electro-Magnetic field. My concern is to create the sleeping quarters 
that are as free from EMF as possible and it seems that a battery 
operated smoke detector placed outside a bedroom door would be better 
in this regard than the hard-wired detector placed inside the 
bedroom.  I've done some poking around, including talking to "Less 
EMF", but haven't come up with any info. Does anyone out there have 
an opinion or a lead of information on this (other than I should stop 
worrying about EMF...)?

Thank you much,
