[The shape of the absorbed dosage in neutron irradiation of a water phantom].
The paper is concerned with the results of experimental and estimated investigations into the spatial distribution of an absorbed dose and the spectrum of neutrons during irradiation of a water phantom by a P-3 beam of a BP-10 reactor. The ratio of densely ionizing and rarely ionizing components of an absorbed dose as well as the ratios between neutrons of different energetic groups were shown to undergo considerable changes with the penetration of reactor neutrons into the depth of a tissue-equivalent medium. The obtained results serve as basic data in various biomedical investigations using reactor neutron beams, including the planning of their use in cancer therapy.
