Standardisation of 241Am activity for a key comparison
نویسندگان
چکیده
Abstract The JRC applied six measurement techniques to standardise the activity of an 241 Am solution in frame 2003 key comparison CCRI(II)-K2.Am-241. methods used were alpha-particle counting at a defined small solid angle, high-efficiency particle and photon with windowless 4π CsI(Tl) sandwich spectrometer, alpha pressurised proportional counter, alpha-gamma coincidence sum counter NaI(Tl) well detector, liquid scintillation counter. All results consistent unusually low uncertainty 0.054% was achieved. An overview is presented outcome exercise, which demonstrates international equivalence.

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
a comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
