We show that energetic charged particles are produced during electrolysis of a D2O solution of Li2SO4 in a cell with a platinum anode and a palladium cathode. CR-39 plastic detectors, designed for recording alpha particles from radon decay, were immersed in the electrolyte during electrolysis. They recorded significantly larger numbers of energetic particle tracks than were recorded by control ...

A novel method for characterising the full spectrum of deuteron ions emitted by laser driven multi-species ion sources is discussed. The procedure is based on using differential filtering over the detector of a Thompson parabola ion spectrometer, which enables discrimination of deuterium ions from heavier ion species with the same charge-to-mass ratio (such as C(6+), O(8+), etc.). Commonly used...

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...

This paper reviews some aspects of solid-state nuclear track detectors (SSNTDs) and their applications in the radon and other research fields. Several geometrical models for the track growth given in the literature are described and compared. It is found that different models give close results for the dimensions of track openings. One of the main parameters that govern track formation is the b...

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...

Large panels of etched plastic, situated aboard the Skylab Space Station and inside Ohya quarry near Tokyo, have been used to set limits on fluxes cosmogenic particles. These plastic particle track detectors also provide best sensitivity for some heavy dark matter that interacts strongly with nuclei. We revisit prior bounds from Skylab, incorporate geometry-dependent thresholds, a halo velocity...

The colorless LR 115 solid-state nuclear track detector (SSNTD) (from DOSIRAD) is based on cellulose nitrate and was first studied in view of its applicability in radiobiological experiments with alpha particles. In this paper, the bulk etch characteristics were studied. We first showed that the shape of the alpha-particle tracks are irregular with blurred contours under the optical microscope....

Purpose: İzmir is the province of Turkey with highest lung cancer incidences for males, therefore a comparative study was performed in particular districts 2013. In study, it aimed to assess association between risk and indoor radon. 
 Methods: Patients diagnosed 2010 2011 were selected from database Izmir Cancer Registry (ICR). Measurements radon concentrations total 117 locations using S...
