Why should the strength of brachytherapy sources be specified in terms of AKS?

Specifying the strength of brachytherapy sources in terms of AKS (Air Kerma Strength) is essential for several reasons. First, using AKS simplifies calculations relevant to treatment planning and dose delivery, as it provides a standardized measurement that can be easily incorporated into various dosimetry formulas and software used in clinical settings. This standardization allows for more straightforward comparisons and consistency across different treatment plans and institutions.

Second, the transition to AKS helps avoid the confusion that can arise from using outdated units, such as curies or radium equivalent, which are less common in modern dosimetry practices. By relying on AKS, practitioners ensure that they are using a contemporary and widely recognized unit that reflects the latest advancements and standards in radiation therapy.

Lastly, specifying strength in AKS diminishes the risk of incidents that can occur due to misunderstanding or miscommunication surrounding various unit measurements. Brachytherapy involves precise dosimetry, and even minor errors in calculation or interpretation related to unit confusion can lead to significant consequences for patient safety and treatment efficacy. By standardizing to AKS, the field enhances the clarity and safety of treatment procedures.

In summary, specifying brachytherapy source strength in AKS promotes accurate and safe practice in medical
