    Measured dose distributions of iodine-125 sources and the computerised optimisation of their positions in brachytherapy planning
    (1987) Rae, William Ian Duncombe; Shackleton, David
    The use of 1-125 seeds in brachytherapy is widespread and becoming increasingly varied. The spatial dose distributions around two types of 1-125 seeds in general use, were measured using a Geiger-Muller chamber. Seeds with the 1-125 adsorbed onto resin spheres had a 10% less anisotropic dose distribution than seeds containing a silver wire with the 1-125 adsorbed onto it. An interpolative method was developed for fast dose calculations taking this anisotropy into account.
