The feasibility of using the active layer of the colorless LR 115 SSNTD for alpha-particle radiobiological experiments was studied. The track revelation time on the bottom side (the side attached to the polyester base) was much longer than that on the top side (the side not attached to the polyester base) of the active layer so track formation on the top side was more desirable. In relation to ...

The radiobiological effect of densely ionizing ends of primary or secondary charged particles may be influenced significantly by processes running in the chemical stage of radiobiological mechanism; especially the influence of present oxygen may be very important. The effect of its or of other species (radiomodifiers) present in water medium during irradiation may be studied with the help of co...

Studies of the structure of particle tracks have led to models of track effects based on radial dose and radiobiological target theory that have been very successful in describing and predicting track effects in physical, chemical, and biological systems. For describing mammalian cellular inactivation two inactivation modes are required, called gamma-kill and ion-kill, the first due to synergis...

Abstract Purpose The aim of this study is to quantify the potential benefits a flattening filter‐free (FFF) beam and implement dose‐computation algorithm for cervical radiotherapy through dosimetric radiobiological analyses using RapidArc. Methods Thirty‐three patients were enrolled, four RapidArc plans created each patient dual‐arc filter 6‐MV FFF photon beams two calculation algorithms. Homog...
