Secondary neutrons in clinical proton radiotherapy: a charged issue.
Hospital-based proton facilities may represent a major advance in radiation therapy, in part because of excellent dose distributions around the tumor, and in part because of the potentially lower whole-body dose compared with photon radiotherapy. Most current proton beams are spread out to cover the tumor using beam scattering and collimation techniques (passive scattering); this will necessari...
متن کاملDose measurement outside of radiotherapy treatment field (Peripheral dose) using thermoluminesent dosimeters
Background: In radiation therapy, peripheral dose or the dose outside the radiotherapy field, is important when anatomical structures with very low dose tolerances are involved. One of these critical organs in pelvic irradiation is testis. The amount of radiation delivered to the testes in radiotherapy must be kept as small as possible, consistent with the limit dose of this organ. The threshol...
متن کاملDose equivalent from 500 MeV neutrons
Neutrons constitute a major component in the radiation fi eld outside the shielding of particle accelerators. Consequently appropriate neutron dose meters are needed to survey the radiation levels. A thermo-luminescence based neutron dosemeter is used at the UNILAC as well as at the SIS. It has been modifi ed to improve the response for high energetic neutrons (extended range). We report on a t...

*Correspondence: Martin-Immanuel Bittner, Department of Radiation Oncology, University Medical Center Freiburg, Robert-Koch-Str. 3, D-79106 Freiburg, Germany e-mail: martin-immanuel.bittner@ uniklinik-freiburg.de Antiprotons have been proposed as possible particles for radiotherapy; over the past years, the renewed interest in the potential biomedical relevance led to an increased research acti...
متن کاملInfluence of secondary neutrons induced by proton radiotherapy for cancer patients with implantable cardioverter defibrillators
BACKGROUND Although proton radiotherapy is a promising new approach for cancer patients, functional interference is a concern for patients with implantable cardioverter defibrillators (ICDs). The purpose of this study was to clarify the influence of secondary neutrons induced by proton radiotherapy on ICDs. METHODS The experimental set-up simulated proton radiotherapy for a patient with an IC...
