Therapy chambers can be calibrated in terms of exposure, air kerma, and absorbed dose to water. This is because these parameters are fundamental to ensuring accurate dose delivery in radiation therapy.

Exposure refers to the amount of ionization produced in air by X or gamma radiation and is key in determining how much energy is delivered to the patient. Air kerma is a measure of the kinetic energy released in a unit mass of air and is essential for calculating dose distribution in air before it is converted to dose in tissue. Absorbed dose to water is particularly relevant for therapeutic applications, as it represents the energy deposited per unit mass of water, which closely approximates the conditions within human tissue.

Therapy chambers designed for these calibrations are specifically constructed to ensure they deliver precise and reliable measurements for these important clinical parameters. Ensuring accuracy in these measurements is critical for patient safety and treatment efficacy in radiation therapy.

The other options do not provide a comprehensive understanding of calibration for therapy chambers. For example, while proportionality and sensitivity are important qualities in measurement devices, they do not specify the actual parameters that are pertinent for treatment planning. Energy levels and radiation type also play a role in therapy and calibration, but they do not account for the calibration standards necessary for ensuring
