Our aim in this study was to verify the absorbed dose to cochlea of the treatment planning system (TPS) during gamma knife radiosurgery of acoustic schwannoma using ionization chamber, diode measurements and a micro diamont detector. The cochlea is a high risk organ which will be saved by treatments of acustic schwannomas by the Gamma Knife radiosurgery unit. Materials and Methods: A human cadaver head and an Alderson phantom were prepared by drilling a hole of 8 mm diameter to the cochlea to pl...

Iwona Pacyniak1, Krzysztof W. Fornalski2, Maria Kowalska11Centrl Laboratory for Radiological Protection, Warsaw2PGE EJ 1, WarsawMixed radiation n+g comes mainly from nuclear reactors. These two types of radiation have different properties and also different biological effectiveness. In case of exposure of people to this kind of radiation it is very important to assess not only the total absorbed dose but also neutron and gamma contribution. It is possible by using iterative method and also bayes...
