Early Biophysical Processes
oral (invited speaker)
Microdosimetry measurements with Tissue Equivalent Proportional Counters (TEPC) are routinely used to characterize the quality of radiation by obtaining distributions of lineal energy y. Radiation fields of therapeutic pencil-like nuclear beams in tissue-like phantoms are complex due to the admixture of secondary protons, neutrons and nuclei produced in fragmentation reactions [1]. We...

Early Biophysical Processes
oral (invited speaker)
Mechanistic modelling of biological effects of ionizing radiation is an important tool complementary to experimental studies that allows testing hypotheses on radiation action and response mechanisms for improving our quantitative understanding of the underlying principles and systems. It helps analyse and interpret experimental observations and plays a crucial role in inter- and extrapolating...

Elucidation of health effects of low dose radiation exposures is one of the most challenging issues of current radiation biology. Establishment of plausible dose-effect relationship for the range of low doses is hampered by numerous factors. Irradiation of humans for experimental purposes has serious ethical barriers. Animal experiments are also restricted. In these circumstances epidemiology,...

Monte Carlo approach in hadrontherapy is widely used for the optimization of transport beam lines and/or dosimetric studies. In most of cases, in the clinical practice, depth dose distributions and lateral dose profiles are provided, without taking into account the biological effects of ionizing radiation.
In case of ion beams, a mixed radiation field is produced, due to projectile...
