       So just how often does your pocket catch fire?

       I wouldn't go bar-hopping with this one in my trousers. But an admirable invention, nonetheless.

       Smoke alarms contain radioactive material, and therefore I would think it would be ill advised to keep one so close to your family jewels all day long.

       [DrCurry] Depends on whether or not you're carrying your voice-activated lighter.   

       Boffo idea, by the way.

       Jakepatterson: Most ionisation smoke detectors use about 10 microCuries of Americium, an alpha emitter. They're usually quite adequately screened by the thin aluminium can they come in - only dangerous if ruptured. Alpha is blocked even by thin, low density materials like paper - the danger would arise if the device is ruptured. The answer is to use an optical absorbtion detector. A well proven and available technology.   

       I actually do carry a small smoke detector and a small halon fire extinguisher and a smoke hood and a Maglite and 30 metres of parachute cord in my hand luggage when I travel.......   

       This proposed device would need some sort of a clip or other gadget to allow it to be hung high up in the room. In a pocket, it might be masked from smoke until it was too late.

       [8/7], they must love you at the security checkpoints.

       wiml: from that list, I would say that he is the one trying to sneak past the checkpoints.
