The ionization chamber's contribution to leakage can be attributed to which factors?

The contribution of the ionization chamber to leakage is primarily influenced by environmental variables and the design of the system. This is because environmental factors, such as temperature, humidity, and pressure, can affect the ionization process and potentially lead to variations in measurements or an increase in leakage. Additionally, the design of the ionization chamber, including its geometry, insulation, and the materials used for construction, plays a significant role in determining how effectively it can contain the ionization process and manage any potential leakage.

Factors such as calibration history and exposure to high doses may indirectly affect the performance and accuracy of the dosimetry system but do not directly contribute to leakage itself. Therefore, understanding that the performance is contingent upon environmental conditions and the mechanical design underscores the importance of these elements in accurately assessing the ionization chamber's contributions to leakage.
