Ionization smoke sensors are the best smoke sensors; however, the small amount of radioactive source they include is no longer desirable since it makes recycling more complicated where the people encountered with radioactive waste. In this study, a conventional ionization type smoke sensor which contained americium-241 radioactive source modelled by Monte Carlo MCNPX code. The absorbed dose rate is calculated by MCNPX code where the human tissue meddled as a soft tissue material. The dosimetry results are comparable with the experimental safety margins. It concluded that if the ionization smoke sensors positioned at a right distance from the human body, so the radiation risk and the exposure hazard can be lower than the exposure level of the background radiation.

Abstract


Ionization smoke sensors are the best smoke sensors; however, the small amount of radioactive source they include is no longer desirable since it makes recycling more complicated where the people encountered with radioactive waste. In this study, a conventional ionization type smoke sensor which contained americium-241 radioactive source modelled by Monte Carlo MCNPX code. The absorbed dose rate is calculated by MCNPX code where the human tissue meddled as a soft tissue material. The dosimetry results are comparable with the experimental safety margins. It concluded that if the ionization smoke sensors positioned at a right distance from the human body, so the radiation risk and the exposure hazard can be lower than the exposure level of the background radiation.
