Vv. Emelyanov, ESTIMATION OF SENSITIVITY IN DETERMINATION OF LOW CONCENTRATIONS OF RADIONUCLIDES IN ENVIRONMENTAL OBJECTS, Radiochemistry, 40(2), 1998, pp. 182-187
Properties are stated of the statistical distribution of the backgroun
d in a setup intended for measurements of small quantities of radioact
ive materials. The concepts ''detection limit'' and ''measuring limit'
' and their statistical meaning are discussed using methods of the pro
bability theory and mathematical statistics. The necessity is shown of
using these concepts in estimating the sensitivity of radiometric equ
ipment and of the determination method as a whole.
