What is the approximate volume of a Farmer type chamber?

The volume of a Farmer type chamber is generally around 0.6 cm³. This specific design is commonly utilized in clinical settings for the measurement of absolute dose in radiation therapy due to its ability to provide accurate and reproducible results across various radiation energies. The volume is significant as it affects the measurement's response to dose distributions, particularly in the context of high-energy photon and electron beams. Understanding the specific volume of the chamber helps practitioners select the appropriate tool for dosimetry measurements, ensuring accuracy in treatment delivery. This chamber's structure allows it to effectively account for the volume averaging effects, leading to reliable dosimetric data.
