Penetration controlled irradiation with ion beams for biological study
Abstract
To investigate the effect of local irradiation on biological systems, an apparatus for penetration controlled irradiation with ion beams was set up. By comparison of ranges of 1.5 MeV/u He 2+ between the theoretically calculated ranges and the practical ranges using chemical and biological materials, it was demonstrated that the range of an ion beam in a biological material could be controlled linearly by changing the distance from the beam window in the atmosphere to a target, although the fluence decreased at the range-end of the ion beams. In addition, the penetration controlled irradiation of tobacco pollen increased the frequency of leaky pollen. The increased frequency of the leaky pollen suggested that damage in the pollen envelope was induced at the range-end.
