Conferencia invitada; IBER 2015, 6-9th September, Aveiro – Portugal; http://iber2015.web.ua.pt/Traditional dosimetry is based on the proportionality between the energy absorbed by
the medium (absorbed dose) and the induced damage. This assumption applies for
relatively high irradiated volumes and requires some equilibrium conditions.
However, for small volumes being relatively far from the central irradiated areas
these conditions are not observed and radiation damage is mainly driven by low
energy secondary species (electrons and radicals) which induce molecular
dissociations via electronic and vibrational excitations, electron attachment and
chemical reactions. We will present here an integrated modelling procedure to
simulate particle radiation tracks including those of all generated secondary species
and their further interactions with the molecular constituent of the medium. For any
selected volume of interest, this model provides not only the total energy transferred
to that area but also the number and type of interactions taking place in it [1].Peer Reviewe
