Description of radiation- and ultrasound-induced cell death by a stochastic process

Radiat Environ Biophys. 2009 Feb;48(1):99-105. doi: 10.1007/s00411-008-0201-0. Epub 2008 Nov 1.


Cell survival is a stochastic process with the stochastic component being strongly dependent on the irradiation conditions. This process is described by a stochastic model which allows differentiation between the deterministic and stochastic components of survival. The proposed model is tested for four irradiation experiments (2 with ionizing radiation and 2 with ultrasound) and very good agreement with experimental results is demonstrated. It identifies the higher stochasticity of the cell survival for the temporally varying radiation fields and provides the possibility to compare the stochasticity of survival in different radiation fields.
