Intense laser-produced plasmas generate bright, ultrashort bursts of accelerated ions. Reducing the required laser intensity and increasing repetition rate to high energy ions is important, mesoscopic particle targets are an attractive option address this issue. Newer experimental strategies measure ion energies their angular distribution needed in studies such systems. In paper, we outline a m...

Introduction: Radon is a colorless inert gas which decay products are the main component of natural radioactive elements that are naturally produced in under layers of earth crust by decay of radium and uranium. It enters through buildings via gaps and cracks. Radon gas decay products like alpha particle can increase the incidence of lung cancer in human. Since every person sp...
Nanosized Co-Cr-V alloy powders were synthesized via coprecipitation method. Effects of precipitants ((NH₄)₂C₂O₄·H₂O and Na₂CO₃) and pH were investigated by X-ray diffraction (XRD), Zeta potential analyzer, thermogravimetry-differential scanning calorimetry (TG-DSC), inductively coupled plasma-atomic emission spectrometry (ICP-AES) and scanning electron microscopy (SEM). Co-Cr-V alloy powders w...
Background: The Poly-Allyl Diglycol Carbonate (PADC) detector is of particular interest for development of a fast neutron dosimeter. Fast neutrons interact with the constituents of the CR-39 detector and produce H, C and O recoils, as well as (n, α) reaction. These neutron- induced charged particles contribute towards the response of CR-39 detectors. Material and Methods: Electrochemical...
Abstract This paper describes cooperation of the Slovak University Technology in Bratislava (STU) and Institute Metrology (SMU) verification calibration factors for solid-state nuclear track detector utilized radon dosimetry establishing traceability STU laboratory. The SMU operates Air Radon Standard which consists a chamber calibrated atmosphere monitoring system. A specification is that conc...
