A Nonparametric Method for the Derivation of α/β Ratios from the Effect of Fractionated Irradiations [PDF]

, 1991
Multifractionation isoeffect data are commonly analysed under the assumption that cell survival determines the observed tissue or tumour response, and that it follows a linear-quadratic dose dependence.
