Ionizer chamber
WebGas-flow ionization chambers for radioisotope (RI) monitoring systems at RI institutes throughout Japan are commonly used to measure RIs which leak from the RI institutes. Before the Japan's 2011 Tohoku earthquake [11 March 2011, moment magnitude (M (w)) 9.0], ionization current data measured with a gas-flow ionization chamber at the RI … WebThe ion charge measured with a free-air chamber under SEE conditions can be converted into the absorbed dose to air using the ionization constant of air (W/e = 33.97 J/C). The following relationship between the air kerma, K a , and the charge, Q/m, measured per unit of mass is obtained:
