Abstract
Applications of the variance-covariance technique are presented that illustrate the potential of the method. The dose mean lineal energy, yD, can be determined in time-varying radiation fields where the fluctuations of the dose rate are substantially in excess of the stochastic fluctuations of the energy imparted. An added advantage is, that yD is little influenced by noise that affects both detectors simultaneously. The variance-covariance method is thus stable with respect to dose rate fluctuations and other temporal variations of a radiation field, and to various influences of noise and electronic artefacts. The dose mean lineal energy obtained at different simulated diameters agrees well with experimental data by other authors and can be determined for small simulated diameters (below 100 nm).
