AI Article Synopsis
- A new method using a strontium (Sr) source was adapted for consistency checks of HDR brachytherapy well-type ionization chambers (WTIC).
- The Sr source was placed on top of the WTIC to establish a reference reading, and measurements were taken to assess variations from this reference.
- This method was validated against calibrated iridium (Ir) source measurements, suggesting a tolerance limit for variation of 1.5%.
Article Abstract
A methodology using aSr source, originally designed for constancy checks of parallel-plate ionization chambers, was proposed for constancy checks of HDR brachytherapy well-type ionization chamber (WTIC). The Sr source was positioned on the top of the WTIC, a reference reading value was established, and the constancy variation was calculated by the difference between each subsequent measurement and the reference value. This methodology was validated by calibrated Ir sources measurements and an acceptable tolerance limit for constancy variation of 1.5% was suggested.
