Alpha Emitter Intrinsic Concentration in Copper required for Nuclear Spectrometry Application
Journal Title: Journal of Nuclear Physics, Material Sciences, Radiation and Applications - Year 2017, Vol 5, Issue 1
Abstract
Low-level radioactivity content in copper are employed for bolometric thermal radiation sensors and astro-nuclear spectrometers. The required lowest achievable alpha emitters concentration, for treated and untreated surfaces, are measured by Double Sided Silicon Strip Detectors in a high vacuum chamber and provide information on its intrinsic NORM content. Results shows that copper alpha emitters content can be achieved in the range below 0.01 (counts. keV-1·kg-1·y-1) adequate for specific nuclear spectrometry applications.

Thermoluminescent Characteristics of Li2B4O7 Doped with Mn2+ and Eu3+ Ions
Analysis of thermoluminescent properties were made for two samples; Li2B4O7, Li2B4O7:Mn2+:Eu3+. These samples were prepared by melt quenching method. The glow curves of the samples show two broad peaks at 160º C and 245...
