Oer For Mixed Neutrons And Γ Rays, Robert Katz, S. C. Sharma Nov 1974

Oer For Mixed Neutrons And Γ Rays, Robert Katz, S. C. Sharma

Robert Katz Publications

A formula for the OER in a mixed field of neutrons and gamma rays (Hall, 1972a; 1972b) is given .... Our results, calculated from track structure theory (Katz and Sharma, 1973) and secondary particle-energy spectra in tissue from these neutrons (Caswell and Coyne, 1973; Dennis, 1972) are within 5 per cent of the values of Omix found from the Hall formula, when that formula is supplied with calculated values of Rn, On, and Oγ, at appropriate survival levels. Our calculations suggest that the Hall formula may be used with confidence for neutrons of …


Cellular Survival In A Mixed Radiation Environment, Robert Katz, S. C. Sharma Aug 1974

Cellular Survival In A Mixed Radiation Environment, Robert Katz, S. C. Sharma

Robert Katz Publications

Calculations of the survival, r.b.e., and o.e.r. of human kidney cells, after sequential irradiation with gamma-rays and 14 MeV neutrons, agree well with the experiments of Railton et al., with CHO cells in these radiation environments.

Les calculs de survie, de EBR et de FAO concernant les cellules du rein humain, après des séquences d’irradiation avec des rayons gamma et des neutrons 14 MeV, concordent bien avec les expériences de Railton et ses collègues sur des cellules CHO dans des milieux comportant les mêmes radiations.

Berechnungen des Überlebens, des RBW und des OER von menschlichen Nierenzellen nach aufeinanderfolgender Bestrahlung mit …


Heavy Particles In Therapy: An Application Of Track Theory, Robert Katz, S. C. Sharma Jul 1974

Heavy Particles In Therapy: An Application Of Track Theory, Robert Katz, S. C. Sharma

Robert Katz Publications

The survival, OER, and RBE for HeLa, leukemia, and kidney cells after irradiation with 14 MeV neutrons, pion beams, and heavy ion beams dispersed by ridge filters are calculated. Simple beam models and the delta-ray theory of cellular survival are used in the calculations, which refer to a mixed radiation environment and the potential application of these irradiation systems in radiotherapy.

Résumé
Particules lourdes en thérapie; une application de la théorie de trace
On a calculé la survie, l’OER et le RBE (efficacité biologique relative) pour les cellules de HeLa, de leucémie et rénales, après l’irradiation aux neutrons de 14 …
