Hello,

Anyone know of any Links where there is information regarding
how safe an Ionization type of Smoke Detector is in a youngster's room.

Looked, but couldn't really find anything specific.

Thanks,

Bob

http://public-blog.nrc-gateway.gov/2...ave-your-life/ says that it's a fraction of a percent of what you're getting anyway from earth and space.

If that still doesn't let you sleep nights, put in a photo-electric instead..

Assuming nobody's smoking in the room (which might deliver more radiation than a smoke detector: http://www.epa.gov/radiation/sources/tobacco.html) the most common source of fires in bedrooms is, I believe, electrical arcs from mis-wired outlets and plugs and cords getting crushed behind and under furniture. These can produce slow, smoky fires that overcome the room occupants as they sleep, before the smoke ever reaches the hallway, which is why smoke detectors are recommended for *inside* the bedrooms.

But the risk of such fires can be greatly reduced with the use of arc-fault breakers, which have been mandated on bedroom circuits in the US & Canada for several years. Check to see if your place has them.

Probably more common than any of the above are injuries from shoddy drop-sided cribs, suffocation under ill-fitting mattresses, and strangulation from nearby power or phone cables or drapery draw cords.
