Spatial dose distributions in water absorber irradiated with high energy nucleons

The technique of numerical calculation of the two-dimensional spatial distributions of full absorbed and equivalent dose in water phantom irradiated with high energy nucleon beams 0.05 <= E <= 10 GeV as well as its components distribution is described. Calculations are performed with the created MEDICA pro gram realizing the method of consecutive collisions copformably to narrow nucleon beams with an arbitrary energy spectrum incident onto the absorber. The calculation results satisfactorily (+-20%) agree with the measurement results and can be used as initial data for calculating microdosimetric energy distributions in the phantom for concrete cond.itions on similar beams
