Fission Fragments Track- Etched Pores in Borate Glass
A study has been made to investigate the detection sensitivity of Borate Glass for the heavily ionizing fission fragment tracks. The latent damage tracks produced by fission fragments in Borate Glass, with and without Aluminium Oxide as an additive, have been studied under a high resolution scanning electron microscope. Tracks have been found and studied only in the Borate Glass samples with no...
متن کاملThyroid cancer after external or internal ionizing irradiation.
It has been known for 50 years that thyroid exposure to high doses of ionizing radiation in childhood and adolescence induces an appreciable cancer risk. Epidemiological studies in children treated with external radiotherapy for benign or malignant lesions in the head and neck have also shown the induction of thyroid cancer. The World Health Organization (WHO) has reported that the risk for dev...
متن کاملCharacterization of Etched Glass Surfaces by Wave Scattering
The roughness of glass surfaces after different stages of etching is investigated by reflection measurements with a spectrophotometer, light scattering, and atomic-force microscopy (in small scale), and Talysurf (in large scale). The results suggest, there are three regimes during etching, according to their optical reflectivity and roughness. The first and second regimes are studied by the Kir...
متن کاملImproved fission-track length measurements using ion irradiation
Apatite [Ca5(PO4)3(F,Cl)] is a common mineral in rocks that contains ~10 ppm U. U disintegrates by spontaneous fission and the fission fragments produce linear damage trails of ~20 μm length and 5-10 nm width. The lattice damage along such a fission track is repaired at elevated temperatures, leading to a gradual decrease of its etchable length. Since fresh tracks are formed as existing tracks ...
متن کاملComparison of removal torques between laser-etched and modified sandblasted acid-etched Ti implant surfaces in rabbit tibias
PURPOSE The purpose of this study was to analyze the effects of two different implant surface treatments on initial bone connection by comparing the Removal Torque Values (RTQs) at 7 and 10 days after chemically modified, sandblasted, large-grit and acid-etched (modSLA), and Laser-etched (LE) Ti implant placements. MATERIALS AND METHODS Twenty modSLA and 20 LE implants were installed on the l...
