This paper describes two mathematical statistic methods for testing the homogeneity of environmental soil sample
i. e. classical variance analysis and "degree of inhomo-geneity" method. The soil samples were analysed by instrumental neutron activation analysis (INAA). The elements determined were Th
La
Cr
Fe
Co. The result of "degree of inhomogeneity" method is discussed in comparison with classical variance analysis.
