This book was released on 2018-08-16 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Track theory is combined with a realistic model of a heavy ion beam to study the effects of nuclear fragmentation on cell survival and biological effectiveness. The effects of secondary reaction products are studied as a function of depth in a water column. Good agreement is found with experimental results for the survival of human T-l cells exposed to monoenergetic carbon, neon, and argon beams under aerobic and hypoxia conditions. The present calculation, which includes the effect of target fragmentation, is a significant improvement over an earlier calculation because of the use of a vastly improved beam model with no change in the track theory or cellular response parameters.

Download or read book Advances in Radiation Biology written by John T. Lett and published by Academic Press. This book was released on 2013-10-22 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in Radiation Biology, Volume 11, provides an overview of the state of knowledge in the field of radiation biology. The book contains eight chapters and begins with a study on ADP-ribose in DNA repair. This is followed by separate chapters on the inhibition of DNA repair; the photochemistry and photobiology of furocoumarins and their applications in biology and medicine; radiation risk from combined exposures to ionizing radiations and chemicals; and in vitro studies of drug-radiation interactions. Subsequent chapters deal with free-radical processes in radiation and chemical carcinogenesis; heavy-ion tissue radiobiology; and radon concentrations in the environment and their impact on health.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: A parametric track structure model is used to estimate the cross section as a function of particle velocity and charge for mutations at the HGPRT locus in human fibroblast cell cultures. Experiments that report the fraction of mutations per surviving cell for human lung and skin fibroblast cells indicate small differences in the mutation cross section for these two cell lines when differences in inactivation rates between these cell lines are considered. Using models of cosmic ray transport, the mutation rate at the HGPRT locus is estimated for cell cultures in space flight and rates of about 2 to 10 X 10-6 per year are found for typical spacecraft shielding. A discussion of how model assumptions may alter the predictions is also presented.
