Abstract
A cloud chamber which can make visible individual ions in the tracks of ..cap alpha.. particles is available at Harwell. Work on the theory of droplet formation and growth has enabled a tissue-equivalent gas of lower density than previously possible to be used in the chamber. This has enabled even the closest ions in ..cap alpha..-particle tracks to be individually resolved. Extensive spatial analysis has been carried out on ..cap alpha..-particle track segments at 5.0, 3.4, and 1.1 MeV. Radial distributions of ionization density with distance from the track have been derived, Rossi Y distributions have been calculated for target sizes of 10 and 50 nm (at 1000 kg m/sup -3/) and, finally, interdroplet distance distributions have been derived. These results may be compared to Monte Carlo calculations of track structure and may also provide useful data for theories of radiation damage.
