Abstract
The validity of using the independent reaction times (IRT) method to d escribe the nonhomogeneous reaction kinetics of complex and spatially correlated systems, such as ionising radiation track segments in liqui d water, is tested. The time-dependent yields of various radiolytic sp ecies obtained with the IRT method are shown to compare well to those of a full step-by-step Monte Carlo simulation code. The good agreement between the two methods still holds as the linear energy transfer of the radiation is increased from 0.3 to 45 keV mu m(-1). (C) 1998 Elsev ier Science Ltd. All rights reserved.
