چکیده

It is well established that the bulk etch rates for solid state nuclear track detectors are a ected by the concentration and the temperature of the etchant. Recently, we found that the bulk etch rate for the LR 115 detector to be a ected by stirring during etching. In the present work, the e ects of stirring on the bulk etch rate of the CR-39 detector is investigated. One set of sample was etched under continuous stirring by a magnetic stirrer at 70◦C in a 6:25 N NaOH solution, while the other set of samples was etched without the magnetic stirrer. After etching, the bulk etch thickness was measured using Form Talysurf PGI (Taylor Hobson, Leicester, England). It was found that magnetic stirring did not a ect the bulk etch of the CR-39 detector, which was in contrast to the results for the LR 115 detector. c © 2003 Elsevier Ltd. All rights reserved.

E ects of stirring on the bulk etch rate of LR 115 detector

The e ects of stirring on the bulk etch rate of LR 115 detector has been investigated. The surface pro6le measurement method using an instrument called Form Talysurf has been used to measure the thickness of the active layer of the LR 115 detectors. The etchant was 10% aqueous solution of NaOH maintained at 60◦C. The bulk etch rate under magnetic stirring has been found to be 6:65 ± 0:34 m h−1 ...

Bulk and track etch properties of CR-39 SSNTD etched in NaOH/ethanol

Recently, Matiullah et al. described the use of NaOH/ethanol as an etchant for the CR-39 detector, and have determined the corresponding bulk and track etch properties from the track diameter method. In the present work, the bulk and track etch properties of CR39 in NaOH/ethanol were derived from direct measurements. The bulk etch rate has been found to increase with the molarity of NaOH/ ethan...

Effects of UVC irradiation on alpha-particle track parameters in CR-39

The effects of UVC exposure on the track etch rate Vt and the detector sensitivity V of CR-39 SSNTDs were investigated through the diameters and depths of alpha-particle tracks. Both the bulk etch rate Vb and Vt increased but V decreased. The track diameters and depths were used to derive a V function for CR-39 detectors with and without UV irradiation. © 2008 Elsevier Ltd.

A fast method to measure the thickness of removed layer from etching of SSNTD based on EDXRF

Solid state nuclear track detectors are commonly used for measurements of concentrations of radon gas and/or radon progeny. All these measurements depend critically on the thickness of the removed layer during etching. However, the thickness of removed layer calculated using the etching period does not necessarily provide a su7ciently accurate measure of the thickness. For example, the bulk etc...

Proton 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...
