Ionization-type smoke detectors are gaseous ionization detectors in widespread use. A small source of radioactive americium is placed so that it maintains a current between two plates that effectively form an ionisation chamber. If smoke gets between the plates where ionization is taking place, the ionized gas can be neutralized leading to a reduced current. The decrease in current triggers a fire alarm. WebThis ionized gas provides current that is directly proportional to the X-ray photon energy. The advantages of the gas ionization detector are high spatial resolution capability and simplicity. In addition, the compact detector assembly can be made on a large scale by packing a few hundred equivalent detector elements that have detector widths as narrow … north bend car dealershipsWebIonization chamber types are calibrated to read exposure levels.
