    Streszczenie angielskie: Heavy-ion radiotherapy is an efficient mthod for the treatment of deep-seated tumors, because the stopping of ions in a tissue delivers the maximal absorbed dose to the tumor-affected areas with minimal damage to the healthy tissues. However, heavy ions can undergo nuclear reactions, giving products with lower Z-values and hence a longer range in the tissue. This causes a dose increase beyond the mean range of the primary beam. The contribuation of such reaction products was examined in an experiment where a stack of tissue-like targets interleaved with CR-39 etched traack detectors (ETD) was irradiated with heavy ions. The analysis was performed using a recently developed technique of trajectory tracing, which enables the spectroscopy of fragments with different Z-values.

    Streszczenie angielskie: The investigation of boron biodistribution by neutron induced autoradiography was performed using a CR-39 etched track detector. Calibration samples, made of boronated chicken liver, and freeze-dried mouse tissue samples were irradiated both with thermal and cold neutrons. Digital images were made on the basis of track densities, with the selection of tracks due to 10BB(n, ŕ)7Li reaction. A comparison of results obtained both with thermal and cold neutrons demonstrated that it is possible to obtain equivalent results with both neutron sources, although the background noise due to recoil protons from the fast neutrons of the thermal neutron source is 15 p.c. higher than that of the cold neutron source. 10B concentrations in the range of 0.5 ppm to 150 pm were determined, with a standard deviation of 13 p.c. and 8 p.c. for the mouse tissue samples and calibration samples, respectively.
