Radon gas, which undergoes radioactive decay, can cause damage to the lung tissue and cancer over time in indoor environments where it is inhaled. gas radioactivity concentrations were measured using CR-39 passive solid state nuclear track detectors (SSNTD) basement ground floor simultaneously summer winter periods 17 dwellings Çanakkale (Turkey). Accordingly, an average of 163.67 Bq.m-3 baseme...

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...

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...

Background: Radon and its daughters are amongst the most important sources of natural exposure in the world. Soil is one of the significant sources of radon/thoron due to both radium and thorium so that the emanated thoron from it may cause increased uncertainties in radon measurements. Recently, a diffusion chamber has been designed and optimized for passive discriminative measurements of rado...

Presently, CR-39 Solid State Nuclear Track Detectors (SSNTD) is being used for Fast Neutron Personnel Monitoring in India. Individual detectors are cut manually from CR-39 sheets. Laser-cutting of the sheets will ensure precision and also save on the laborious efforts involved in sheet cutting. It was observed that there is a slight increase in background tracks due to laser-cutting. Studies we...

One approach for a particle radiobiological experiments is to use solid-state nuclear track detectors (SSNTDs) as support substrates to record the a particle hit positions on the targets. To facilitate accurate characterization of the hit positions as well as the incident a particle energies, micro-collimators are required in these experiments to restrict the incidentaparticles to thosewith sma...
