A versatile gamma ionization chamber (VGIC) has been designed, developed and characterized, in order to study experimentally its characteristics according to the geometry of the electrodes, the volume and pressure of the filler gas for the design of a gamma sealed chamber. The tests were conducted under the IEC (International Electro-technical Commission). The results obtained in various nuclear tests of the characterization and calibration of the ionization chamber gamma VGIC developed at our laboratory were presented in this paper. Three irradiators were operated, irradiator intensive gamma (⁶⁰Co: 1.25 MeV), medium intensive gamma (¹³⁷Cs: 0.662 MeV) and low-intensity gamma (⁶⁰Co). Saturation curves and linearity were identified and the operating range and the sensitivity of the chamber have been deducted. The current, voltage (I,V) characteristics of the chamber filled, with argon gas at 0.4 M pa pressure, for gamma ray irradiator sources were studied, the chamber was irradiated with gamma rays using different gamma sources. The plateau region is reached above 200 V and the detector operating voltage is found to be 600V. It is observed that in the plateau region the slope is constant with an increase in the exposure rate. The (1/I, 1/V) and (I, l/V²) characteristic curves reveal the presence of the initial and volume recombination losses. The volume recombination losses are found to be smaller than the initial recombination losses.

设计、开发和表征了多功能伽马电离室 (VGIC)，以便根据电极的几何形状、用于设计伽马密封室的填充气体的体积和压力，通过实验研究其特性。测试是在 IEC（国际电工委员会）下进行的。本文介绍了在我们实验室开发的电离室伽马 VGIC 的表征和校准的各种核试验中获得的结果。操作了三个辐照器，辐照器强伽马（⁶⁰ Co：1.25 MeV）、中强伽马（¹³⁷ Cs：0.662 MeV）和低强度伽马（⁶⁰合）。确定了饱和曲线和线性，并扣除了操作范围和腔室的灵敏度。研究了腔室的电流、电压 (I,V) 特性，其中充有 0.4 M pa 压力的氩气，用于伽马射线辐照源，使用不同的伽马源对腔室进行伽马射线辐照。平台区域达到 200 V 以上，检测器工作电压为 600 V。观察到，在高原地区，斜率随着曝光率的增加而恒定。(1/I, 1/V) 和 (I, l/V ² ) 特性曲线揭示了初始和体积复合损失的存在。发现体积复合损失小于初始复合损失。
