Ionization Chamber Designing

#Ionization_Chamber is an efficient tool for indirectly measuring the dose of high-energy rays such as #Alpha, #Beta and #Gama and detecting the presence of #Radioactive substances in the environment. #Radioactive_materials emitting high-energy radiation can ionize the surrounding air. If we measure the amount of ionization, we can measure the dose of radiation and confirm or deny the presence of radioactive materials in the environment. This efficient tool is used by all International Atomic Energy Agency (#IAEA) inspectors and other regulatory agencies. The various operating modes of this device include “#open_air” and “gas trapped in the #Geiger_müller_tube”. The second method has a simpler electrical circuit, but due to the nonlinear relationship between the circuit voltage and the ionization load, calibration is very difficult and has only diagnostic applications. In the first method, the “open air” method, the ionization chamber environment is associated with the complete ambient air. The electrical circuit of this method is more complicated. In addition, due to the lower voltage of the High Voltage circuit, the current due to ionization is very small compared to the second method. To collect this current, a very fine circuit is needed to measure currents around “multi femto Amps”. Today and after many years, I am proud that i was the #hardware_designer of a system with the resolution of “3 femto Amps”. A successful #Teamworking with experts such as #Arman_Safikhani and other specialists like #mechanical_Designers and #nuclear_physicists. I share with you the joy.
