Track detection on the cells exposed to high LET heavy-ions by CR-39 plastic and terminal deoxynucleotidyl transferase (TdT)
Background: The fatal effect of ionizing radiation on cells depends on Linear Energy Transfer (LET) level. The distribution of ionizing radiation is sparse and homogeneous for low LET radiations such as X or γ, but it is dense and concentrated for high LET radiation such as heavy-ions radiation. Material and Methods: Chinese hamster ovary cells (CHO-K1) were exposed to 4 Gy Fe-ion 2000 keV/...
متن کاملProton beam dosimetry by CR-39 track-etched detector
Background: High and intermediate energy protons are not able to form a track in a solid state nuclear track detector (SSNTD) directly. However, such tracks can be formed through secondary particles created during primary radiation nuclear reactions in a SSNTD. Materials and Methods: The protons with primary energies of 9.6 and 30 MeV available at the cyclotron accelerator with corresponding lo...
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 کاملNuclear 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 کاملComputer program TRACK_VISION for simulating optical appearance of etched tracks in CR-39 nuclear track detectors
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 ...
