Abstract. In this work, the detection limits for the
radioactivity
counting are determined. Several decision rules are presented and
applied
to calculate the critical value. The value obtained by the best
approximation
for the alpha particles counting, was used to evaluate the minimum
detectable
concentration in: water, soil and air.
Key words: detection
limits, radioactivity counting.
GRANICE DETEKCIJE ZA BROJANJE ALFA
ČESTICA
U radu su određene granice detekcije za merenje radioaktivnosti pomoću
brojača ? / ? čestica. Prikazana su različita pravila odluke i
primenjena
pri izračunavanju kritične vrednosti. Vrednost dobijena korišćenjem
najbolje
aproksimacije za obavljeni eksperiment brojanja ? čestica, primenjena
je
u proračunu minimalne merljive koncentracije za: vodu, zemlju i vazduh.
