11. The ionization chamber utilized electrodes with a total surface area of about 1000 cm 2. 12. Ionization chamber type smoke detectors detect particles of combustion that are invisible to the naked eye.13. In 1908, Villard pioneered the use of an ionization chamber for the dosimetry of ionizing radiation. 14. It is the americium isotope used in an americium smoke detector based on an ionization chamber . 15. The team created a multilayer ionization chamber to detect decay products originating from the fission of uranium. 16. An ionization chamber type smoke detector is technically a product of combustion detector, not a smoke detector. 17. For gamma emitters either an ionization chamber , a gamma spectrometer or an energy compensated GM tube are required. 18. This equipment bears his name today as the : Shonka ionization chamber , the Shonka electrometer, and Shonka plastics. 19. It is widely used in commercial ionization chamber smoke detectors, as well as in neutron sources and industrial gauges. 20. Advanced equipment had been prepared, its main parts were a telescope consisting of 30 Geiger-Muller meters, and an Ionization chamber .
