The modifying action of caffeine on the effect of fast neutrons in human cells

The cytogenetic data obtained indicate a real possibility to intensify damage of the human cells as affected by rapid neurons. It can be achieved by combination of reparation inhibitors (caffeine) and rare-ionizing radiation (gamma rays) and is expressed in 5.5-fold increase of yield of chromosome damages in caffeine case and in increase of yield of exchange aberrations in the case of combination with gamma radiation.
