Ionisation Distribution for Nanometre Subcellular Volumes Irradiated by High LET Parallel Beams

Publikováno v: Radiation Protection Dosimetry. 32:119-122

Radiation energy deposited in or around nanometre-sized subcellular volumes, such as sections of DNA molecules, is considered to be responsible for the initiation of cell mutations and cell killing. A computer simulation methodology is here presented

Spatial Distribution Patterns of Energy Deposition and Cellular Radiation Effects in Lung Tissue Following Simulated Exposure to Alpha Particles

Autor: W. Hofmann, M. Nösterer, D.J. Crawford-Brown, A. Hutticher

Publikováno v: Radiation Protection Dosimetry. 31:413-420

Randomly oriented sections of rat tissue have been digitised to provide the contours of tissue-air interfaces and the locations of individual cell nuclei in the alveolated region of the lung. Sources of alpha particles with varying irradiation geomet

Stochastic state-vector model of radiation carcinogenesis applied to radon-induced lung cancer risk

Autor: D.J. Crawford-Brown, Werner Hofmann

Publisher Summary A biophysical multi-stage state-vector model (SVM) of radiation carcinogenesis has been extended to incorporate stochasticity of transitions and spatial inhomogeneity of cellular doses. Dose-rate dependent cellular transitions betwe

Data collection, validation, and description for the Oak Ridge nuclear facilities mortality study

Autor: D.J. Crawford-Brown, J.L. Reagan, J. P. Watkins, W. G. Tankersley, D.L. Cragle, C. M. West, E. L. Frome

To investigate the long-term health effects of protracted occupational exposure to low levels of ionizing radiation, a mortality study was initiated by pooling data for 118,588 workers hired between 1943 and 1982, at three Department of Energy (DOE)

Estimating dose rates to organs as a function of age following internal exposure to radionuclides

Autor: L.R. Williams, D.J. Crawford-Brown, M. Cristy, Keith F. Eckerman, Richard W. Leggett, D.E. Dunning

The AGEDOS methodology allows estimates of dose rates, as a function of age, to radiosensitive organs and tissues in the human body at arbitrary times during or after internal exposure to radioactive material. Presently there are few, if any, radionu
