Alpha particle radiation sensor. a silicon diode radiation sensor is used to check the radioactive source in a smoke detector. according to the label, the source is given as 1 mu, ci. the source is am-241 with an energy of 5.486 times 10^6 ev and an activity of 12.95 times 10^10 bq. the energy needed to generate an electron-hole pair is 3.61 ev. the diode is connected to an inverse potential of 12 v, has a thickness of 0.5 mm, and the mobility's are 450 cm^2/v-s for holes and 1350 cm^2/v-s for electrons. the radiation from am-241 is mostly a particles that penetrate very little into the silicon and hence may be assumed to be absorbed at the surface of the diode. for this reason the junction is exposed directly so radiation does not pass through the electrodes. what is the current through the diode if all particles emitted are trapped by the diode?
