In spite of small geometrical dimensions of the ionization chambers, the sensitivity distribution throughout the entire chamber must be considered if conditions are extreme (small size of field, short distances). Various types of chambers were studied with regard to their response threshold along their axis. Taking the different wall thicknesses into consideration, different ionization chambers show good agreement with regard to the accumulation effect of Co-60 gamma radiation.
尽管电离室的几何尺寸较小，但在极端条件下（小射野尺寸、短距离），仍必须考虑整个电离室内的灵敏度分布。针对各种类型的电离室沿其轴的响应阈值进行了研究。考虑到不同的壁厚，不同的电离室在钴 - 60γ 辐射的累积效应方面表现出良好的一致性。
