Differences in electron beam dosimetry using two commercial ionization chambers and the TG‐21 protocol: Another reason to switch to TG‐51

Two of the most popular dosimetry systems used for calibration of megavoltage photon and electron beams in radiation therapy are (i) cylindrical Farmer‐type chambers in liquid water and (ii) Holt Memorial parallel‐plate chambers in clear polystyrene. Since implementation of the AAPM TG‐21 calibratio...
