Characterization of an in vivo diode dosimetry system for clinical use.

An in vivo dosimetry system that uses p-type semiconductor diodes with buildup caps was characterized for clinical use on accelerators ranging in energy from 4 to 18 MV. The dose per pulse dependence was investigated. This was done by altering the source-surface distance, field size, and wedge for photons.

Photon shielding for a positron emission tomography suite.

This paper provides information on the effects of distance and attenuation in lead sheet and gypsum board of the 0.511 MeV photon produced by positron annihilation. Exposure rates are projected external to an adult injected with 185 MBq (5 mCi) of 18F in a fluorodeoxyglucose solution and for the same activity in a small unshielded container.

The use of Teflon-embedded calcium sulphate: dysprosium thermoluminescent dosimeters for chest radiography.

As part of a U.S. multi-regional pilot study conducted by the six Centers for Radiological Physics, 12-mm-diameter by 0.

A technique for routine calibration of thermoluminescent dosimeters in the diagnostic energy range.

Four different techniques for calibrating lithium fluoride thermoluminescent dosimeters were compared at two beam qualities in the diagnostic energy range. The techniques included in-air, saturation backscatter, and Bureau of Radiological Health (BRH) test stand geometry with and without an ionization chamber. The results indicate that there are no statistical differences between any of the calibration techniques evaluated.
