The application of experimental microdosimetry to mixed-field neutron-gamma dosimetry
Al-Bayati, Saad Najm (2012-12-01)Absorbed dose distributions in lineal energy for neutrons and gamma rays were measured by using both a tissue-equivalent walled counter (TEPC) and a graphite-walled low pressure proportional counter (GPC) in the Am-Be ... -
Design and characterization of next-generation tissue equivalent proportional counters for use in low energy neutron fields
Ali, Fawaz (2014-04-01)Tissue Equivalent Proportional Counters (TEPCs) are devices that can measure the radiation dose levels for the mixed neutron and gamma ray fields that are encountered in nuclear facilities. TEPC designs typically consist ... -
Design and construction of a one-dimensional particle tracker for measurement of alpha particle stopping power
Watt, Sarah (2019-08-01)The energy deposited by a charged particle in a medium is non-uniform and peaks near the end of the particle’s path. The energy deposition through the medium is known as stopping power and the shape of this function is ... -
Dosimetric characterization of a miniature x-ray source for biophysics studies
Virdi, Karanvir Singh (2015-07-01)Tritium is a low energy beta emitter that is found in abundance at CANDU nuclear power plants and is a cause of concern since it accounts for roughly thirty three percent of the total occupational exposure of nuclear ... -
The effect of high dose rate on tissue equivalent proportional counter measurements in mixed neutron-gamma fields
Qashua, Nael (2010-04-01)Tissue equivalent proportional counters (TEPCs) are commonly used for radiation monitoring in areas where a mixture of neutron and photon radiations may be present, such as those commonly encountered in nuclear power plants. ... -
An experimental study of the relative response of plastic scintillators to photons and beta particles within the context of tritium monitoring
Kumar, Ashita (2011-08-01)A scintillation counting system has been constructed with the use of BC-400 and EJ-212 series plastic scintillators along with a subminiature photomultiplier tube to investigate the effect of increasing plastic scintillator ... -
An investigation of early radiation damage in exposed eye-lenses of rainbow trout
Kocemba, Marta (2019-08-01)The objective of this work is to contribute to the study of radiation effects in non-human biota and potentially to the study of eye-lens damage in humans by investigating the effects of low-energy X-rays on the lenses of ... -
Optimization of a GEM-based detector to measure tritium and discriminate against other radiation types
Dhinakar, Arvind (2019-11-01)Tritium poses a radioprotection issue, in the Canadian Nuclear industry due to the operation of its fleet of Canadian Deuterium Uranium (CANDU) heavy water reactors. Although it is a less penetrative radionuclide, tritium ... -
Radiation response and optical characterization of carbon based thin-films prepared by saddle field plasma enhanced chemical vapor deposition
Hegazy, Sameh (2020-09-01)Carbon based thin-film materials have been attracting a lot of attention in many research fields due to their unique material properties. Detection of ionizing radiation is an important application that carbon and diamond ... -
Simulation, design and construction of a gas electron multiplier for particle tracking
Sipaj, Andrej (2012-12-01)The biological effects of charged particles is of interest in particle therapy, radiation protection and space radiation science and known to be dependent on both absorbed dose and radiation quality or LET. Microdosimetry ... -
Theoretical performance analysis of a novel hemispherical tissue equivalent proportional counter for neutron monitoring and dosimetry
Broughton, David (2016-02-01)Neutron dosimetry in reactor fields is currently conducted using thermal neutron flux monitors. It has been demonstrated that Tissue Equivalent Proportional Counters (TEPCs) have the potential to improve the accuracy of ...
