The homogeneity of fertilizer samples for
interlaboratory γ-ray spectrometry comparison was tested
by determination of the total γ count rate and the count
rates for two 238U γ lines, one 40K line and one common 235U and 226Ra line. Homogeneity testing was accomplished
by determination of the minimum, maximum, mean and
standard deviation for each parameter and comparison
of their standard deviations with predefined tolerances,
by Cochran’s test, and by a one-way ANOVA. The standard
deviations were all less than these tolerances. All samples
passed Cochran’s test and the one-way ANOVA test
for homogeneity.
