Effectiveness of a fast neutron beam to induce DNA damage in Ehrlich ascites carcinoma cells irradiated in a aqueous phantom

The study of damages to DNA molecules of Ehrlich ascites tumor cells exposed in water phantom to fast neutron beam (mean energy of 6 MeV) showed that changes in the extent of DNA injury did not correlate with the absorbed dose distribution at the phantom depth of 8-12 cm, and also that the dose-response function in the phantom was different from that obtained upon irradiation of cells in the air.
