Neutron dosimetry with planar silicon p-i-n diodes
New nonionizing energy losses (NIEL) sensors based on silicon planar p-i-n diodes of different geometry have been investigated and their response to fast neutron field compared with bulk diodes. The… Expand

OBJECTIVE We have shown previously that pretreatment with genistein potentiated cell killing induced by radiation in human PC-3 prostate carcinoma cell line in vitro. We tested this approach in vivo… Expand
Progression of renal cell carcinoma is inhibited by genistein and radiation in an orthotopic model
BackgroundWe have previously reported the potentiation of radiotherapy by the soy isoflavone genistein for prostate cancer using prostate tumor cells in vitro and orthotopic prostate tumor models in… Expand
Simultaneous macro and micro dosimetry with MOSFETs
The application of MOSFET dosimeters in complicated mixed radiation fields for measurement of absorbed dose distribution in tissue equivalent phantoms has been studied. The spectra of secondary… Expand
Potential Hazard Due to Induced Radioactivity Secondary to Radiotherapy: The Report of Task Group 136 of the American Association of Physicists in Medicine
Abstract External-beam radiation therapy mostly uses high-energy photons (x-rays) produced by medical accelerators, but many facilities now use proton beams, and a few use fast-neutron beams.… Expand

- 1 February 2001
We have shown previously that genistein, the major isoflavone in soybean, inhibited the growth of human prostate cancer cells in vitro by affecting the cell cycle and inducing apoptosis. To augment… Expand
RBE variation between fast neutron beams as a function of energy. Intercomparison involving 7 neutrontherapy facilities.

In fast neutron therapy, the relative biological effectiveness (RBE) of a given beam varies to a large extent with the neutron energy spectrum. This spectrum depends primarily on the energy of the… Expand
Characteristic 8 keV X Rays Possess Radiobiological Properties of Higher-LET Radiation
Abstract Electronic brachytherapy systems are being developed that can deliver X rays of varying energy depending on the material of a secondary target. A copper target produces characteristic 8 keV… Expand
