Description
  • The contribution of high linear energy transfer (L) charged particles to dosimetric and microdosimetric characteristics in a clinical proton beam was experimentally studied using an ionization chamber and track etched detectors. The particles mentioned are produced by proton nuclear interactions; at the Bragg peak region slowed down protons also contribute in the L region above several keV µm-1. Due to these particles the biological weighted effective dose (BWED) of the beam changes with depth. The spectra of particles with L above 7 keV µm-1 were established by means of track etched detectors, which permitted us to determine their contribution to dosimetric and microdosimetric characteristics of clinical proton beams. The studies were realized in the clinical proton beam of the JINR Dubna Phasotron, with a primary energy of 205 MeV.

  • Příspěvek nabitých částic s vysokým lineárním přenosem energie (L) k dozimetrickým a mikrodozimetrickým charakteristikám v klinickém svazku protonů byl studován s využitím ionizačních komor a detektorů stop. Zmíněné částice vznikají interakcemi protonů a jader; v oblasti Braggova píku přispívají také zpomalené protony. V důsledku těchto částic se biologicky vážená efektivní dávka (BWED) ve svazku mění s hloubkou. Spektrum částic s L nad 7 keV µm-1 bylo měřeno pomocí detektorů stop, které dovolují určit jejich příspěvek k dozimetrickým mikrodozimetrickým charakteristikám klinických protonových svazků. Studie byly provedeny v klinickém svazku protonů v SÚJV Dubna, primární energie protonů byla 205 MeV. (cs)
