A computer program called TRACK_VISION for determining the optical appearances of tracks in nuclear track materials resulted from lightion irradiation and subsequent chemical etching was described. A previously published software, TRACK_TEST, was the starting point for the present software TRACK_VISION, which contained TRACK_TEST as its subset. The programming steps were outlined. Descriptions ...

Fossil tracks of charged particles have been observed in minerals separated from the Vaca Muerta mesosiderite. Irradiation of samples of the meteorite with thermal neutrons in a nuclear reactor, together with measurements of track-length distribution, indicate that some of the tracks result from the spontaneous fission of uranium impurities; others, however, are of different origin. Uranium con...

Several natural minerals contain trace amounts of uranium. Spontaneous nuclear fission of U causes the formation of particle (fission) tracks along the trajectories of the ejected nuclear fragments. The lattice damage along a fission track is repaired at elevated temperatures, leading to a gradual reduction of its etchable length that depends foremost on the highest temperature that the track h...

Is There a Spatial Component to Nuclear RNA Processing and Transport? A controversial model holds that the RNA processing machinery resides at defined locations in the nucleus and that RNA transcripts travel on defined paths through these sites on their route to the cytoplasm. Thus, transcription, processing, and transport into the cytoplasm would occur in an ordered fashion as transcripts move...

Abstract A nuclear emulsion film is a three-dimensional tracking device that widely used in cosmic-ray and high-energy physics experiments. Scanning with wide angle acceptance crucial for obtaining track information films. This study presents new method developed high-speed recognition of films neutrino–nucleus interaction measurements. The technique can be to measure tracks charged particles f...

ABSTRACT  Background: The essential constituents of cements like lime, silica and alumina are derived from earth’s crust in which radioactive elements like uranium, thorium etc are also present in varying amounts almost everywhere. These two elements are considered as the parent elements of uranium and thorium radioactive decay series in which radon and thoron are produced respectively as decay...
