“…A number of studies have evaluated different detector types for the dosimetry of low energy photon beams (Fletcher and Mills, 2008;Guillerminet et al, 2005;Healy et al, 2005;Hill et al, 2008;Hugtenburg et al, 2001;Jurado et al, 2005;Li et al, 1997;Ma et al, 1998;Nelson et al, 2008;Prestwich and Murphy, 2000;Rink et al, 2007;Sellakumar et al, 2009). There are limited recommendations by which a new detector should be tested in order that it can replace a gold standard detector.…”
