Lanthanum Bromide Scintillation Detector for Gamma Spectrometry Applied in Internal Radioactive Contamination Measurements
نویسندگان
چکیده
Apariţia de noi tipuri de detectori cu scintilatori anorganici LaBr3(Ce) şi LaCl3(Ce), a generat necesitatea testării lor pentru diferite aplicaţii. Ca o alternativă a detectorului NaI(Tl), utilizat, în mod tradiţional, în sistemele gama de monitorizare a I-131, în tiroidă, a fost considerat pentru caracterizare, un detector LaBr3(Ce), de dimensiuni 1.5“ x 1.5”. Rezultatele au fost evaluate, urmarindu-se conturarea unui raspuns referitor la potrivirea unui astfel de detector pentru detecţia I-131 în tiroidă. Au fost obţinute spectre comparative pentru cei doi detectori, NaI(Tl) si LaBr3(Ce), în aceeaşi geometrie de măsură.

Cerium, neodymium and gadolinium contain double beta active isotopes. The most interesting are Nd and Gd (promising for 02 search), Ce (2 candidate with one of the highest Q2). The main problem of compounds containing lanthanide elements is their high radioactive contamination by uranium, radium, actinium and thorium. The new generation 2 experiments require development of methods for a de...
متن کاملRadioactive contamination of scintillators
Low counting experiments (search for double β decay and dark matter particles, measurements of neutrino fluxes from different sources, search for hypothetical nuclear and subnuclear processes, low background α, β, γ spectrometry) require extremely low background of a detector. Scintillators are widely used to search for rare events both as conventional scintillation detectors and as cryogenic s...
