To investigate the variability and stability of brachytherapy source strength calibration coefficients for air‐communicating and pressurized well‐type ionization chambers among high‐dose rate (HDR), low‐dose rate (LDR), and electronic brachytherapy (EBT) source qualities. These qualities of an ionization chamber are important features to assess given their role in maintaining traceability to a primary national standards laboratory and facilitating efficacious patient care in brachytherapy.

关于稳定型电离室的离子源强度标定系数。

研究高剂量率（HDR），低剂量率（LDR）和电子近距离放射治疗（EBT）来源质量之间的空气流通和加压井式电离室近距离放射治疗源强度校准系数的变异性和稳定性。考虑到电离室在保持对主要国家标准实验室的可追溯性以及促进近距离放射治疗中有效的患者护理方面所起的作用，因此这些质量是评估的重要特征。
