Design of an Ytterbium-169 brachytherapy source for gold nanoparticle-aided radiation therapy
… of external x-ray beams from a Philips RT-250 orthovoltage x-ray machine in an attempt to match the dosimetric characteristics of the Ytterbium-169 brachytherapy source. This investigation will enable the production of an external beam that can serve as a good surrogate of an actual …

Dielectric liquid ionization chambers for detecting fast neutrons
… detectors were exposed to 250keV x-rays from an orthovoltage x-ray tube and neutrons (1.4-12MeV) from a 1-Ci 239Pu-Be source. Experimental data show that an ionization chamber filled with dielectric liquid is capable of detecting fast neutrons in pulse mode. While chamber 1, chamber 2, and …

Understanding The Influence of Photon Energy On 6Mv Non Reference Dosimetry and Ct Dosimetry Using Tld and Osld
… are often referenced to a therapy-energy or orthovoltage photon beam – commonly 250kVp, Co-60, or even 6MV, where the spectra are substantially different. Appropriate calibration techniques specifically for the OSLD nanoDot in a CT environment have not been presented in the literature; …
