Heavy Ion Effects on Cells: An Approach to Theoretical Understanding
Heavy charged particles constitute an important part of the cosmic space radiation field. An understanding of their biological action is not only of fundamental interest but also a necessary prerequisite for a rational approach to radiation protection in space. It is the purpose of this paper to lay the ground by outlining a theoretical approach which is exemplified by experimental data with yeast obtained in our laboratory. Open questions will be discussed in the final section. Although the treatment is directed to biological cells it may also be applicable to components of electronic microcircuits which are comparable both in size and sensitivity.
