The Interaction between Radioactive Ions and Condensation Nuclei

[摘要] To clarify the interaction between radioactive ions and condensation nuclei, simultaneous measurements of the concentrations of radioactive ions, radioactive aerosols, condensation nuclei, and small positive ions were carried out on the top of Mt. Norikura and the campus of Nagoya University. The mean life of radioactive ions is 38 sec on the top and 14 sec on the campus, respectively.The concentration of radioactive ions correlates positively with that of small positive ions and negatively with that of condensation nuclei. These correlations may be well expressed by the following simple formulae; q=βnZ and q0=β0n0Z.
