The common type of household smoke detector contains a small amount of Am-241, which is a decay product of plutonium-241 originating in nuclear reactors. The Am-241 emits alpha particles which ionise the air and allow a current between two electrodes.

Many nuclear processes produce two photons simultaneously, while other processes produce two or more photons in quick succession. WebSo, for U-235 for example, when it decays via α-decay, a Geiger counter will only detect it if there is no 'window' on the detector as alpha particles cannot penetrate through solid matter very far. Scintillation counters can use different materials specialized for specific types of radiation as well. dr thombre chembur
