The well-type ionization chamber has been designed for convenient use in brachytherapy source strength calibration. The chamber has a volume of 240 cm, weight of 2.5 kg, and is open to atmospheric conditions. The well-type ionization chamber dosimetric characteristics such as leakage current, stability, scattering effect, ion collection efficiency, and nominal response with energy were studied. The evaluated dosimetric characteristics of well-type ionization chamber were compared with two other commercially available well-type ionization chambers. The study shows that the newly developed well-type ionization chamber is reliable for air-kerma strength calibration. The results obtained confirm that this chamber can be used for the calibrations of high-dose rate brachytherapy sources.

Absolute gamma-ray emission intensities for 36 characteristic gamma rays from the decay of Ra, Pb, and their progeny were determined by measuring sources calibrated for activity by means of primary methods based on well-defined high-purity germanium (HPGe) detectors at both NIST and NPL. Results from the two laboratories agree with recent data evaluations, except for gamma rays with low emission intensities. The decay schemes have been re-balanced based on the new results.

Article Synopsis
- This technical report discusses the quality control status of iodine (I) seed source strength measurement for Permanent Prostate Brachytherapy in Japan, highlighting issues with traceability in source strength assessments.
- A working group was formed by JASTRO in 2021 to tackle the challenges faced by medical facilities, including a lack of consistent source strength verification, with a survey revealing that 41% of facilities do not confirm the number of seeds or measure source strength.
- The report emphasizes the importance of the single-seed assay as a reliable method for ensuring traceability, noting that most facilities in Japan do not utilize this standardized measurement technique.
