CASE SCENARIO:
The meltdown of Chernobyl's nuclear fission plant inApril 1986 caused a dispersal of 137Cs (Caesium) between Ukraineand Sweden. The highest amounts of radiation were measured in thenorth region, where fallout percolated into sandy topsoils withrainwater. by using the Phytoremediation method suggest theeconomic considerations and conclusion for thisproject.
