Nuclear Track Detectors
Approximately half of the human exposure to radiation is due to indoor airborne shortlived progeny (decay products) of the radon gas (Rn). To measure the airborne concentrations of radon gas and/or its progeny, Nuclear Track Detectors (NTDs) are usually employed. The NTDs register the alpha particles emitted by radon gas and its progeny in the form of tracks in the NTDs, which will become visib...
متن کاملSearch for Anomalons Using Plastic Nuclear Track Detectors
We exposed a stack of CR39 track detectors containing Ag foils to a 1.7 GeV/nucleon 56Fe'beam and investigated the anomalous mean free path effect. Neither the whole set of 7517 nor a subset of 2542 interacting fragments produced probably in the Ag target show an effect. By combining the data of this and an earlier experiment we can also exclude an effect for 3219 interacting fragments produced...
متن کاملBulk Etch Rate Measurements and Calibrations of Plastic Nuclear Track Detectors
New calibrations of CR39 and Makrofol nuclear track detectors have been obtained using 158 A GeV Pb and In ions; a new method for the bulk etch rate determination, using both cone height and base diameter measurements was developed. The CR39 charge resolution based on the etch-pit base area measurement is adequate to identify nuclear fragments in the interval 7 ≤ Z/β ≤ 49. For CR39 the detectio...
متن کاملEngineering cell-fluorescent ion track hybrid detectors
BACKGROUND The lack of sensitive biocompatible particle track detectors has so far limited parallel detection of physical energy deposition and biological response. Fluorescent nuclear track detectors (FNTDs) based on Al₂O₃:C,Mg single crystals combined with confocal laser scanning microscopy (CLSM) provide 3D information on ion tracks with a resolution limited by light diffraction. Here we rep...
متن کاملNuclear Track Detectors for Particle Searches
In this paper we report a search for intermediate mass magnetic monopoles and nuclearites using CR39 and Makrofol Nuclear Track Detectors (NTDs) of the SLIM large area experiment, 440 m exposed at the high altitude laboratory of Chacaltaya (Bolivia) and about 100 m at Koksil, Himalaya (Pakistan). We discuss the new chemical etching and improved analysis of the SLIM CR39 sheets. Preliminary limi...
