[en] The experimental data determination of distribution ¹³⁷Cs, ⁹⁰Sr, ^239+240Pu, ²⁴¹Am 'Chernobyl' releases and ²³⁰,²³²Th on the fraction of humic and fulvic acids sandy- podsolic, meadow and peaty soils taken in the exclusive zone ChNPP are presents. Soils organic matter was isolated by conventional alkali extraction (Turin's method). It was shown that, with depending of soils types 15-45 % ²⁴¹Am associate with fulvic acids. In all investigated types of soils 30 - 40 % ^239+240Pu connects with humic acids, as strong complexes. The distribution of environmental ²³⁰,²³²Th and artificial ^239+240Pu on the fraction natural organic species is the same
