Stochastic behaviour of a cell survival with n-sensitive regions of nucleus and cytoplasm

This paper considers the stochastic behaviour of a living cell having two compartments, namely, the nucleus and cytoplasm exposed to radiation. Each compartment is made up of n-sensitive regions. It is usual to assume that there exists a sensitive volume of the cell in either the nucleus or the cytoplasm. An ionizing event or a hit within this volume initiates changes in either the nucleus or the cytoplasm. No doubt that the change in the nucleus or in the cytoplasm is possible through the change within the regions of these two compartments. These changes bring the cell either in the partially normal (partially damaged) state or in the abnormal (completely damaged) state. Several characteristics of the cell survival are studied using the regenerative point technique.
