[P210] Track structure-based corrections for ionization quenching in scintillators exposed to ions

Track detection on the cells exposed to high LET heavy-ions by CR-39 plastic and terminal deoxynucleotidyl transferase (TdT)

Background: The fatal effect of ionizing radiation on cells depends on Linear Energy Transfer (LET) level. The distribution of ionizing radiation is sparse and homogeneous for low LET radiations such as X or γ, but it is dense and concentrated for high LET radiation such as heavy-ions radiation. Material and Methods: Chinese hamster ovary cells (CHO-K1) were exposed to 4 Gy Fe-ion 2000 keV/...

Semi-empirical calculation of quenching factors for scintillators: new results

New results of calculation of quenching factors for ions in scintillators in semi-empirical approach described in [1] are presented. In particular, they give additional arguments in favour of hypothesis that quenching factors for different particles can be described with the same Birks factor kB, if all the data were collected in the same conditions and processed in the same way.

Approaches to Track Structure

In attempting to understand the chemical and biological effect* of ionizing radiation it is natural to consider first the most characteristic feature of the energy transfer process, namely, the concentration of energy along the tracks of charged particles whether these are the primary radiation itself /fast electron beams, alpha particles, heavy ions/ or the secondaries produced within the mate...
