Diffusion kinetics of radical intermediates in radiation chemistry

W Naumann, W Stiller - International Journal for Radiation Physics and …, 1976 - Elsevier
Almost all theoretical papers on the mechanism of radical reactions in the tracks of ionizing
particles implicitly assume the independence of the radical distributions. In this paper the …

A simplified approach to diffusion-controlled radical reactions in the tracks of ionizing radiations

A Mozumder, JL Magee - Radiation Research, 1966 - JSTOR
From quite elementary considerations, the present authors have conclu that the track
generated by an ionizing particle in the low over-all LET r be considered as composed of a …

Theory of radiation chemistry. III. Radical reaction mechanism in the tracks of ionizing radiations

AK Ganguly, JL Magee - The Journal of Chemical Physics, 1956 - pubs.aip.org
This paper develops a model for the dissipation of the tracks of high‐energy particles. It is
assumed that all chemical effects are due to one kind of radical and that there are no effects …

Model of tracks of ionizing radiations for radical reaction mechanisms

A Mozumder, JL Magee - Radiation Research, 1966 - JSTOR
The" string of beads" model for the track of an ionizing particle as propose Samuel and
Magee (1) has, in the past, been widely used for the discussion of sion-controlled reactions …

Stochastic model based on pair distribution functions for reaction in a radiation-induced spur containing one type of radical

P Clifford, NJB Green, MJ Pilling - The Journal of Physical …, 1982 - ACS Publications
A model for reaction in radiation-induced spurs, containing one type of radical, is developed
which uses stochastic methods. The reactants are considered in pairs, and the rate of …

Kinetics in radiation chemistry

A Hummel - Radiation chemistry, 1987 - inis.iaea.org
[en] In this chapter the authors first briefly review the kinetics of first-and second-order
processes for continuous and pulsed irradiation, without taking the effects of …

Numerical treatment of the kinetics of track processes in radiation chemistry

MR Pollak, RH Schuler - Radiation Physics and Chemistry (1977), 1984 - Elsevier
It is shown that the time dependence of the population of intermediates that react within
radiation tracks can be approximated quite well as the sum of a finite series of exponential …

Kinetics of radical recombination

AA Belyi, AA Ovchinnikov - Theoretical and Experimental Chemistry, 1967 - Springer
A general equation is obtained describing the time change in the concentration of reacting
particles. Solutions are given for different initial conditions corresponding to characteristic …

Approximate Solutions to the Diffusion-Kinetic Equations

FE Haskin, RE Faw - Nuclear Applications, 1969 - Taylor & Francis
The partial differential diffusion-kinetic equations describing the diffusion and reaction of
chemically active species along the tracks of ionizing radiation are discussed. The few …

Monte Carlo simulation of diffusion and reaction in radiation-induced spurs. Comparisons with analytic models

P Clifford, NJB Green, MJ Pilling - The Journal of Physical …, 1982 - ACS Publications
Reaction in radiation-induced spurs, containing one type of radical, is simulated by using
random walks on a cubic lattice. The simulations are shown to agree satisfactorily with …
