80 µCi Americium-241 Sources Inside Old Pyrotronics F3/5A Smoke Detectors

These are pictures of the Americium-241 sources inside some old Pyrotronics F3/5A smoke detectors that were being decommissioned.  The activity of the Am-241 sources at the time of manufacture (1970s) totaled  80 µCi, so they should still have some ~70 µCi left in them. The Pyrotronics F3/5A smoke detectors were manufactured in the early 1970s. The
