The Relative Biological Effectiveness of Fast Neutrons in Mice
Radiation Research, 1956During the past fifteen years a number of experiments have been done to compare the biological effectiveness of neutron and electromagnetic radiations; however, no consistent pattern has been evident in the various organisms and different radiations used.

The relative biological effectiveness of out-of-field dose
Physics in Medicine and Biology, 2015using simulations and models derived from existing literature, this work investigates relative biological effectiveness (RBE) for out-of-field radiation and attempts to quantify the relative magnitudes of different contributing phenomena (spectral, bystander, and low dose hypersensitivity effects).

Relative biological effectiveness of proton beams in clinical therapy
Radiotherapy and Oncology, 1999In clinical proton beam radiation therapy, an RBE of 1.1 relative to megavoltage X-rays is currently being employed at most treatment centers. This RBE pertains to radiation in the spread out Bragg-peak (SOBP) for all tissue systems, all dose levels per fraction and all proton beam energies. As the number of centers and treatment sites for which proton

Relative Biological Effectiveness: Review of a Model
1988To understand why different energy doses are necessary to bring about the same biological effect by different radiations can be considered as the crucial issue of radiation biophysics. For example, the early target theory had remained a rather abstract and ambiguous scheme until D.E.

Relative biological effectiveness of alpha particles at radon exposure
Radiation Protection Dosimetry, 2015The relative biological effectiveness (RBE) of alpha particles at radon exposure is estimated by comparison of radiation risks at external gamma exposure and radon exposure in different situations. For external gamma exposure, the BEIR VII model of radiation risk assessment was used.

The Relative Biological Effectiveness of Attenuated Protons
1993The 250 MeV Synchrotron at Loma Linda University Medical Center has been in operation since October 1990. In this paper we will report the data collected for survival of V79 cells suspended in gelatin exposed to 100 MeV protons that are attenuated with varying thicknesses of polycarbonate plastic.

Fission Fragment Relative Biological Effectiveness for Liver Tumor Induction
Health Physics, 1995The risk coefficients for liver tumors as derived from 60 beagles with body burdens of 249Cf or 252Cf were used to determine the relative biological effectiveness of fission fragments relative to alpha particles. For liver malignancies the relative biological effectiveness was calculated to be about 2 +/- 3.
