There two main types of smoke detectors in operation;
- Photoelectric: Detect visible particles of combustion and contain no radioactive material.
- Ionisation: Detect invisible particles of combustion and contain a very small amount of radioactive material.
There are currently no legal restrictions placed on the disposal of photoelectric smoke detectors, however the disposal of commercial quantities of ionisation smoke detectors must abide by local and state regulations for radioactive waste.
