Replacement correction (P(repl)) for ion chamber dosimetry.
The use of replacement correction when depth dose distribution is measured with a cylindrical ion chamber is discussed. A review of relevant data shows that the displacement of the effective point of measurement is an appropriate method to make replacement correction for the entire depth ionization curve.
