Advanced Physics for Brachytherapy 2018

Chapter 3: Calibration of Brachytherapy Sources

3.3 In-air measurement technique

3.4 Calibration using well type chambers

3.5 Calibration using solid phantoms Measurements in solid phantoms are not suitable for low-energy sources.

3.6 Relative measurements Readings of consecutive source deliveries can be compared and deviations larger than 3% or 5% should be investigated. Serious incidents may be identified before treatment.
