Commercial alpha- emitting  Smoke detectors rely on alpha radiation from americium-241, which ionizes the Since there is no longer a natural source of 241Pu, 241Am is not being formed. The AFR source standard mounting is in a type A-2 capsule with a 9.5 mm active diameter. The active element for Am-241 consists of a rolled monolithic foil in  AMERICIUM-241 (Am-241) ALPHA RADIOACTIVE SOURCES WITH NIST CERTIFICATE.

Alpha Transitions The energies of the alpha transitions have been calculated from the Q value and the level energies given in Table 1 from 1995Ak01, with corrections for the 8 lower levels to take into account the adopted energies of gamma transitions from section 2.2.

Note: If the video source is to be connected in parallel with other equipment, disable the input termination by turning the corresponding DIP switch to the up position (OFF). Failure to do so may cause reduced image quality.
