Dose rate in water 1 cm transverse to an 125 I seed calibrated for air kerma strength is not well established; 125 I dosimetry calculations are, however, based on this constant. The specific dose constant was obtained from a series of dose rate measu

The purpose of this study was to investigate the application of the Monte Carlo technique to the calculation and analysis of output factors for electron beams used in radiotherapy. The code EGS4/BEAM was used to obtain phase-space files for 6, 12 and

From June 1978 to June 1986, 50 patients with primary and recurrent mycosis fungoides were treated with total skin electron irradiation (TSEI), using the Stanford technique, to a total dose of 3600 cGy. TSEI was used alone, or in combination with low

Documented problems with loose and inert Ir-192 seeds in nylon ribbons prompted us to develop a quality control program. lieveral problem cases are illustrated. A sample of ribbons from each shipment is measured in a radioisotope dose calibrator. Res

Of 33 patients who had undergone allogeneic bone marrow transplantation during first complete remission of acute nonlymphocytic leukemia, 21 patients have now been followed in continued complete remission for 6- 64 mo (median greater than 18 mo) with

We describe the dosimetric characteristics of a newly introduced dual photon energy linear accelerator, the Varian Clinac 1800. Depth doses are compared with other accelerators of the same nominal accelerating potentials (6 and 10 MV). Field flatness

Total body irradiation (1000 rad, single dose) in conjunction with chemotherapy and bone marrow transplantation is a therapy for acute leukemia. We show that a 10 MV linear accelerator is a suitable source of radiation for these procedures. Dosimetri

Attenuation in Lipowitz's metal of x rays produced at 2, 4, 10, and 18 MV and gamma rays from cobalt 60 were measured to the 1% level with a narrow beam geometry. Blocks made from standard styrofoam mold (7.6 cm thick) would reduce these primary beam
