Source For a Low-Cost Source
Re: Source For a Low-Cost Source
Some things to keep in mind.
Americium is an alpha source. The SBM-20 tube used in the kit is primarily sensitive to beta and gamma radiation. The tube will not respond to alpha particles, only the small amount of radiation from decay products.
Americium is also extremely dangerous if ingested, so be extremely careful. It's not recommended to disassemble smoke detectors.
