I need to do a science project for my school, and I have a Geiger Counter so I figured I could use that, I'm aware that smoke detectors use radiation to detect smoke, but I don't have a spare smoke detector to take apart to get the radioactive material, I do have a spare carbon monoxide detector but I'm not sure if that also uses radiation?
Answer
No, they don't use any radioactive substances.
I'd try using granite and other Uranium and Thorium containing minerals, also potassium based fertiliser or salt substitute (Potassium 40 is radioactive and naturally present in all potassium) and gas lantern mantles containing thorium (some gas mantles use less efficient or more expensive alternatives due to fear of radiation).

can you please answer!! abt carbon monoxide!!?
Sarah
basically i woke abt an hr ago to the sound of the carbon monoxide alarm beeping! it isnt very loud and it beeps every 40 seconds. is there carbon monoxide in the house or is it just the battery????? i dont think it would b the battery cuz we just got the alarm less than 3 months ago!! please answer!! would it make a louder noise if there was carbon monoxide here?? thanks and have a great day!!!!!!!!!!
Answer
CO detectors also detect smoke. When a battery gets low the detector usually chirps once every few minutes or so. Every 40 seconds doesn't sound right, the unit may be defective, or they designed it to be more insistent when you have a low battery.
If the alarm was detecting something that needed to be announced the alarm would be beeping rapidly - continuously until the battery went dead. Since yours isn't doing that I'd have to guess it's probably safe to still be in the house.
My wife just bought a new clock. Came with a new battery. But it wasn't working. She was going to take it back but I thought why not just switch the battery. Turned out the contacts were dirty and only needed to be cleaned. Sometimes you get a defective device. I've had plenty of NEW batteries that were almost dead when I took them out of the package. Could just be you need a new battery. No telling how long that thing sat on the shelf - or even if someone bought it and decided they didn't want it any longer. Or maybe they had an old one and bought a new one then put the old one back in the box and brought it back for a refund. These ARE hard economic times and there's no telling what someone may do.
My advice is if the device is acting suspiciously (as I suspect based on the 40 second chirp) I'd think it might be time to either read the instructions or take it back for a new one.
Hope this helps.
