Relative Effectiveness of Mixed Radiation Fields

Relative effectiveness of mixed radiation fields.

For all one-hit detectors the relative effectiveness of a mixed radiation field may be found as the dose-weighted average of the relative effectiveness of its components, segregated according to the atomic number Z and the energy T. We emphasize that this procedure is incorrect for mammalian cells, whatever the nature of the segregation.

relative biological effectiveness (rbe) of 131i radiation relative to 60co gamma rays

objective: to assess relative biological effectiveness (rbe) of 131i radiation relative to 60co gamma rays in glioblastoma spheroid cells. materials and methods: in this experimental study, glioblastoma spheroid cells were exposed to 131i radiation and 60co gamma rays. radiation induced dna damage was evaluated by alkaline comet assay. samples of spheroid cells were treated by radiation from 13...

Design and calibration of a passive detector for separating neutron, proton and alpha particles in mixed radiation fields

In this study, calibration process was carried out for deigned new CR-39 nuclear track detector for protons, neutrons and alpha particles separately under the same etching condition. In order to aim this purpose, americium-beryllium standard source (241Am-Be) and Plexiglas phantom for neutron irradiation, brass collimators and americium standard source (241Am) for alpha irradiation and the acce...
