[en] Detailed dose equivalent distributions have been calculated in the ICRU sphere by Monte Carlo methods for photons in the energy range 0.010 - 10.0 MeV using the kerma approximation, with statistical accuracy generally better than +- 1%. Results are presented as depth-dose distributions along the principal axis and other selected axes and as isodose distributions, for parallel unidirectional, parallel opposed, planar rotational, planar isotropic and spatially isotropic irradiation. Various DE quantities are discussed and their numerical values presented as functions of photon energy. Six appendices are included which discuss (I.) conversion factors for different basic normalisation quantities, (II.) briefly the Monte Carlo procedure used, (III.) the meaning of kerma and the kerma approximation, (IV.) a comparison of the work presented in this report and the calculations of Dimbylow in 1983, (V.) a test experiment using a 30 cm spherical phantom, (VI.) the results of backscatter measurements and calculations using a 30 cm spherical phantom and cubic phantoms.
