“…Boron may be easily introduced by using p doped Si arrays as proposed by Rosenfeld. 7 The introduction of nitrogen into the body of a silicon diode is a much more difficult proposition. Nitrogen concentrations required for an acceptable probability of nitrogen capture are too high for maintaining device operation.…”

“…7 This paper demonstrates that extensive study of charge collection in micron sized silicon volumes may lead to the creation of a new class of microdosimeters for high LET radiation fields. A tissue equivalence correction method for BNCT has been determined but further work is required to investigate the tissue equivalence of silicon microdosimeters in other high LET environments such as heavy ion, fast neutron and proton therapy modalities.…”

Reverse-biased silicon p-n junction arrays have been proposed as microdosimetry detectors. The tissue equivalence of such detectors in boron neutron capture therapy ͑BNCT͒ is discussed. A comparison of the range-energy relationships of H, He, C, and Li ions in tissue ͑ICRU-muscle͒ and silicon is given. A simple geometrical scaling ͑ϳ0.63͒ of linear dimensions is required to convert microdosimetric energy deposition measurements performed in silicon to equivalent deposition in tissue. The Monte Carlo technique is used to examine energy deposition for two simple geometrical cases applicable to BNCT.

“…In this case, a silicon detector of a large area with 7 microns thickness was used. A new approach for silicon microdosimetry based on arrays of silicon SVs (pn-junctions) was proposed by McNulty and Roth [7] for separation of gamma and neutron fields (no microdosimetric spectras was produced) and later SOI microdosimeter was developed and applied to hadron therapy by Rosenfeld [11].…”

“…Silicon microdosimetry was initially developed in the space radiation effects community [8] and was subsequently applied to conventional microdosimetry studies in hadron therapy applications [9]. A prototype silicon microdosimeter was developed which consists of an array of microscopic pn junctions fabricated on varying thicknesses of silicon-on-insulator (SOI) wafers.…”
