A Comparison of Mechanism-Inspired Models for Particle Relative Biological Effectiveness (RBE)
Medical Physics, 2018 Background and SignificanceThe application of heavy ion beams in cancer therapy must account for the increasing relative biological effectiveness (RBE) with increasing penetration depth when determining dose prescriptions and organ at risk (OAR) constraints in treatment planning.

International Journal of Radiation Oncology Biology Physics, 2000 This study aims at providing relative biological effectiveness (RBE) data under reference conditions accounting for the determination of the "clinical RBE" of protons.RBE (ref. (60)Co gamma-rays) of the 200 MeV clinical proton beam produced at the National Accelerator Centre (South Africa) was determined for lung tolerance assessed by survival after ...

Relative Biological Effectiveness (RBE) Values for Proton Beam Therapy
International Journal of Radiation Oncology Biology Physics, 2002Clinical proton beam therapy has been based on the use of a generic relative biological effectiveness (RBE) of 1.0 or 1.1, since the available evidence has been interpreted as indicating that the magnitude of RBE variation with treatment parameters is small relative to our abilities to determine RBEs.

Northern peoples can receive elevated radiation doses (1- 10 mSv/y) from transfer of polonium-210 (210Po) through the lichen-caribou-human food chain. Ingested 210Po is primarily blood-borne and thus many of its short range alpha particles irradiate the endothelial cells lining the blood vessels.

Determination of Relative Biological Effectiveness (RBE) of Soft X Rays
Radiation Research, 1977Differences in clinical results reported with the use of iodine-125 encapsulated implants compared to those with gold-198, radon-222, and iridium-192 prompted a study of the RBE, relative to60 Co γ radiation, of X rays simulating the spectral distribution of radiation from encapsulated125 I.

Relative biological effectiveness (RBE) of 30 MeV electrons at varying depths in tissue
The British Journal of Radiology, 1974Abstract Using the stunting of vertebral growth of one-week-old inbred WHT/Ht mice as the biological test material and Fricke's ferrous sulphate method for dose measurements, the biological effectiveness of 30 MeV electrons relative to 250 kVp X rays has been found to be in the region of 0·82. No difference of statistical significance has been observed

Neutron doses at 0.43 MeV and at a lower average energy level were plotted against x-ray doses required to produce equal effects in various frequencies of response for eight somatic aberrations found in Tradescantia stamen hairs. Such plots serve as a useful graphic method for expressing RBE values which change as a function of absorbed dose.
