They contain a very small amount of radioactive material known as Americium-241. Photoelectric-type smoke detectors do not contain any  radioactive material.

On your wall at home, smoke detectors presents no danger. If they get broken open in a landfill, the material can pose a health hazard.

What happens to recycled smoke detectors?

Detectors are sent to Curie Environmental. They safely dispose of the radioactive material in a designed landfill and recycle the remaining metals and plastics.
