    Oxygen (O6+) ion beam irradiation effects on etching parameter in lexan polymeric track detector

    No full text
    The polymer Lexan was irradiated to 80MeV O6+ ion beam using the 15UD pelletron at Inter University Accelerator Centre, New Delhi. The ion fluence ranging from 1011 to 3 × 1012 ions/cm2 has been used to study the dose effects of irradiation on Lexan. By using the etching technique, it is observed that the bulk etch rate of the sample increases with increasing the ion influence, while the activation energy associated with it show a decreasing trend which can be explained on the basis of polymer degradation.Neerja* and Surinder Singh Department of Physics, Guru Nanak Dev University, Amritsar-143 005, Punjab, India E-mail : [email protected] of Physics, Guru Nanak Dev University, Amritsar-143 005, Punjab, Indi

    Uranium concentration in drinking water samples using the SSNTDs

    Uranium concentrations in the drinking water samples collected mainly from hand pumps along the Amritsar to Bathinda track are presented. Uranium concentration values in these samples show a wide range of variation depending upon different factors like source, location, depth and local geology etc. The observed uranium content in water samples has been found to be varying from 0.9 ± 0.08 to 63 ± 0.21 ppb and even the radon activity in ground water observed in our earlier survey carried out in this area has been found to be increasing from Amritsar towards Bathinda. The higher values were observed from the ground water samples particularly of the areas falling in belt from Zira to Maur towards the Haryana border. The values observed at certain locations are found to be higher than the highest recommended value of 15 ppb [1]. The high uranium concentration observed particularly in certain areas along this track can be attributed due to interaction of ground water with the soil formation of this region and the local subsurface geology of the region.Harmanjit Singh*, Joga Singh, Surinder Singh and B S Bajwa Department of Physics, Guru Nanak Dev University, Amritsar-143 005, Punjab, India E-mail : [email protected] of Physics, Guru Nanak Dev University, Amritsar-143 005, Punjab, Indi

    Justice Nijjar’s long journey in the Indian judiciary represents a diversity of roles and cases to which he brought his leadership. His judgments and contributions made him one of the most outstanding legal minds. Today, we must celebrate his innovation and vision, and how it transformed the way we look at many aspects of justice, especially alternative dispute resolution in India
