Neutron dosimetry with a water calorimeter
In certain situations neutron radiotherapy has potential advantages over conventional X-ray therapy. It has yet to be conclusively proven that neutron therapy is more efficacious than X-ray therapy, and in many institutions worldwide neutron therapy is currently being evaluated. It is important …

Neutron dosimetry, moderated energy spectrum, and neutron capture therapy for ²⁵{45}R²Cf medical sources
Examination of neutron dosimetry for 252Cf has been conducted using calculative and experimental means. Monte Carlo N-ParticIe (MCNP) transport code was used in a distributed computing environment as a parallel virtual machine (PVM) to determine the absorbed neutron dose and neutron energy spectrum …

Theoretical performance analysis of a novel hemispherical tissue equivalent proportional counter for neutron monitoring and dosimetry
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 neutron dosimetry in these reactor fields, and Multi-Element Tissue Equivalent …

A new approach to neutron spectrometry with multi-element scintillators
… design and performance. Currently, there is no neutron dosimeter/spectrometer that can meet the requirements in terms of size and performance. In particular, the requirements for high sensitivity, spectroscopic features, and determination of operational quantities to enable radiation protection …

Design and testing of a novel neutron survey meter
… which can estimate the effective dose of a neutron field, accounting for both direction and energy of the field. This work represents a novel, real-time, approach to workplace directional neutron dosimetry. A 6Li-loaded scintillator based detector system was developed. This detector system …

Monte Carlo calculation and analysis of neutron and gamma fields at spallation neutron sources for simulating cosmic radiation
The research of the neutron induced Single Event Effect (SEE) at aircraft altitudes or at ground level are very important since the neutron radiation is able to cause serious errors or damages on electronic components and system. TheWeapons Neutron Research (WNR) facility at Los Alamos Neutron …

Design and characterization of next-generation tissue equivalent proportional counters for use in low energy neutron fields
… 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 which is composed of tissue-equivalent material. The response of a TEPC …
