Hot particle dosimetry using a wall-less tissue equivalent proportional counter
… their energy over very small distances in tissue making dose determinations through measurement or computation to the target tissues at risk such as epithelial cells in lung and gut and basal cells in skin difficult. Furthermore, current methods fail to determine changes that might occur in …

Theoretical performance analysis of a novel hemispherical tissue equivalent proportional counter for neutron monitoring and dosimetry
… flux monitors. It has been demonstrated 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 …

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 …

Quantifying Uncertainty In A Measurement-Based Assessment of Relative Biological Effectiveness In Carbon Ion Radiotherapy
… (RMF), and Local Effect Model I (LEM) using a Tissue Equivalent Proportional Counter (TEPC).</p> <p>Microdosimetric spectra, kinetic energy spectra, and dose fragment contributions were calculated using Monte Carlo (GEANT IV) for monoenergetic and SOBP carbon beams of clinical energy. From …

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 …

Development of Lineal Energy Spectrum-Based Biological Effects Models for Protons
… compared to experimental measurements made by a tissue equivalent proportional counter and demonstrate reasonable agreement. A method to sum monoenergetic lineal energy spectra to yield the lineal energy spectrum of a polyenergetic beam is described and validated. The summation approach for …

Uncertainty In The Physical Basis of Estimates of Relative Biological Effectiveness In Carbon Radiotherapy
<p>Carbon ion radiotherapy is a novel modality used for the treatment of tumors that are unresectable, close to critical structures, or resistant to standard radiotherapy. A unique benefit of this therapy is the relative biological effectiveness (RBE) of the beam (i.e., how biologically potent …

Design and implementation of the Hybrid Detector for Microdosimetry (HDM): Challenges in readout architecture and experimental results
… 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 literature. A …
