The nuclide 241Am is used in smoke detectors. As it decays (with a half-life of 458 years), the emitted alpha particles ionize the air. When combustion products enter the detector, the number of ions changes and with it the conductivity of the air, setting off an alarm. If the activity of 241Amin the detector is 3 × 104 Bq, calculate the mass of 241Am present.
