Description
  • Pro odhad úvazku efektivní dávky z vnitřní kontaminace 241Am se používá exkreční analýza a metody měření in vivo. Ke stanovování aktivity americia v lebce se používají různé detekční systémy v různých detekčních geometriích. Na SURO je používáno uspořádání dvou polovodičových LEGe detektorů které jsou umístěny 3 cm od spánkové kosti. Pro kalibraci detekčního systému bylo použito několik fantomů lebky, a přitom bylo zjištěno, že detekční účinnost je významně závislá na jejich velikostí. Cílem tohoto článku je vyjádřit tuto závislost, a tím získat přesnější určení aktivity kostře současně se snížením nejistoty měřené hodnoty. (cs)
  • Excretion analysis and in vivo measuring methods are used for estimation of internal contamination by 241Am. Americium activity in the skull is measured with various geometries, which depend on the available instrumentation. Setting of two semiconductors detector placed 3 cm over temporal region of the skull is used in NRPI. Calibration of the system was done by several head phantoms, in this process was observed that detection efficiencies depend on size of the phantoms. The aim of the paper is to express character of the efficiency as function of the size of skull in order to obtain more accurate value of the activity and decrees its uncertainty
