Effects of etching time on alpha tracks in solid state nuclear track detectors.
Solid State Nuclear Track Detectors (SSNTDs) are used extensively for monitoring alpha particle radiation, neutron flux and cosmic ray radiation. Radon gas inhalation is regarded as being a significant contributory factor to lung cancer deaths in the UK each year. Gas concentrations are often monitored using CR39 based SSNTDs as the natural decay of radon results in alpha particles which form t...
متن کاملFactors affecting the registration and counting of alpha tracks in solid state nuclear track detectors
In view of the fact that the radon progeny contribute the highest to the natural radiation dose to general populations, large scale and long-term measurements of radon and its progeny in the houses have been receiving considerable attention. Solid State Nuclear Track Detector (SSNTD) based systems, being the best suited for large scale passive monitoring, have been widely used for the radon gas...
متن کامل3-D imaging of particle tracks in solid state nuclear track detectors
It has been suggested that 3 to 5% of total lung cancer deaths in the UK may be associated with elevated radon concentration. Radon gas levels can be assessed using CR-39 plastic detectors which are often assessed by 2-D image analysis of surface images. 3-D analysis has the potential to provide information relating to the angle at which alpha particles impinge on the detector. In this study we...
متن کاملSolid State Nuclear Track Detectors and Their Applications
I am happy to announce today that the Department’s proposal to set up a Dr Homi Bhabha National Institute has been approved. This will bring together ten premier institutions all over the country under a single research-driven framework. This will help ensure that our scientists and our scientific establishments remain at the forefront of the pursuit of excellence, comparable with the best glob...
متن کاملDigital System to Characterize Solid State Nuclear Track Detectors
A digital system to characterize solid state nuclear track detectors(SSNTD) has been developed. It was used in the study of two detectors and its performance evaluated by comparing the obtained results with those determined by using an analog system, already in use for such purpose. The comparison of the results together with the feasibility and rapidness in data acquisition have demonstrated t...
