When the voltage difference between the electrodes in an ion chamber is low, the tendency for ion recombination is increased because of a weaker electric field, and measured ionization current will not represent a complete ion collection. WebThe initial recombination in an ionization chamber was simulated by a computer model based on Jaffe's theory, where the ionization chamber, with a gap of 0.01 m, is filled with carbon dioxide at the pressure of 4480 mm(Hg) at the temperature of 19.5 °C and is irradiated with polonium a - particles*, that is g = 1.96, and
