Mulching as a countermeasure for crop contamination within the 30 km zone of Chernobyl Nuclear Power Plant

Article Abstract:

Researchers sought to determine what effect mulch soil covers would have on reducing radioactive contamination of cover crops. For three years (1992-1994) oats (Avena sativa) was planted in Kopachy, Ukraine, which is 5 km south of the Chernobyl nuclear power plant. The land is contaminated with cesium137, and condensed particles. One test involved placing a plastic net over the soil. This test significantly increased crop yield, and reduced crop contamination by about 30 percent. Straw mulch was used in a second test with similar results. From these studies, mulching has been shown to reduce contamination and improve crop yields.

Particle and plutonium mobilization in macroporous soils during rainfall simulations

Article Abstract:

Particle and plutonium mobilization in macroporous soils have been found to be unrelated to soil composition with plutonium content of particles decreasing with depth and plutonium transport largely attenuated in the upper 15-20 cm soil level. Rainfall simulations were conducted in three soil pits at the Rocky Flats Plant in Colorado and results show that macropore flow dominates infiltration.
