Design and characterization of next-generation tissue equivalent proportional counters for use in low energy neutron fields
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 of a low density gas sensitive volume surrounded by a solid wall, each of …

Investigation and use of dual (twin) low pressure proportional counters for active neutron-gamma mixed field dosimetry
… Tissue equivalent proportional counters (TEPCs) have been used, but their accuracy is limited. In this study, a custom-built Cylindrical Graphite Proportional Counter (Cy-GPC) along with a twin Cylindrical TEPC (Cy-TEPC) has been extensively investigated for n-γ mixed field dosimetry. …

Design and implementation of the Hybrid Detector for Microdosimetry (HDM): Challenges in readout architecture and experimental results
… the microdosimeter used in this work, i.e. the TEPC or Tissue Equivalent Proportional Counter, a gas microdosimeter that is equivalent in terms of energy deposition to 2 um of tissue. A comprehensive characterization of the TEPC response to different ions and energies can be found in the …

The application of experimental microdosimetry to mixed-field neutron-gamma dosimetry
… using both a tissue-equivalent walled counter (TEPC) and a graphite-walled low pressure proportional counter (GPC) in the Am-Be neutron source facility at University of Ontario Institute of Technology. A series of measurements were performed with the counters filled with propane-based TE gas …

Theoretical performance analysis of a novel hemispherical tissue equivalent proportional counter for neutron monitoring and dosimetry
… that Tissue Equivalent Proportional Counters (TEPCs) have the potential to improve the accuracy of neutron dosimetry in these reactor fields, and Multi-Element Tissue Equivalent Proportional Counters (METEPCs) could reduce the size of instrumentation required to do so. The current METEPC …

Development and Maintenance of the Thymic Epithelial Microenvironment
… by the thymic epithelial progenitor cells (TEPCs). Apart from TEPCs, thymic microenvironment maintenance is also regulated via different signal transduction pathways. In this current study, we focused on understanding the key players in maintaining the thymic epithelial microenvironment. Our …

The effect of high dose rate on tissue equivalent proportional counter measurements in mixed neutron-gamma fields
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. In such radiation fields, the dose rate of each component can vary …
