Cartographical investigations of the territory of radium production waste storage has shown some changes in lateral differentiation of radionuclides of uranium and thorium decay series to occur during 27 years (1981-2008). Those changes are caused mostly by flat denudation typical for fluvial terrace. At present radionuclides of uranium and thorium decay series are concentrated mostly in flood lands and relief depressions. At the same time, decrease in the radionuclide activity concentration in 0-20 cm soil layer is observed with changes in lateral distribution. Total stocks of 226Ra, 210Pb and 210Po within catena soils studied in the northern and southern parts of the waste storage decreased 3-6 times, 238U - 2 times, and did not significantly change in case of 232Th during 27 years. Nonetheless, most of the samples studied are referred to radioactive waste both according to Russian standards (SPORO-2002) and IAEA safety norms (IAEA, 2004).
对镭生产废料储存区域的制图调查显示，在27年（1981 - 2008年）间，铀和钍衰变系列放射性核素的横向分异出现了一些变化。这些变化主要是由河流阶地典型的平面剥蚀造成的。目前，铀和钍衰变系列的放射性核素大多集中在泛滥地和地貌低洼处。与此同时，随着横向分布的变化，在0 - 20厘米土层中观察到放射性核素活度浓度降低。在27年里，储存库北部和南部研究的链状土壤中，226Ra、210Pb和210Po的总存量减少了3 - 6倍，238U减少了2倍，而232Th的情况没有显著变化。尽管如此，根据俄罗斯标准（SPORO - 2002）和国际原子能机构安全规范（国际原子能机构，2004年），所研究的大多数样品仍属于放射性废物。
