Lab clean-up methods help resettlement efforts on the Marshall Islands

 

Narrator:       This is Science Today. Through soil cleanup methods led by the Lawrence Livermore National Laboratory, residents of the Pacific region's Marshall Islands, where nuclear testing took place in the 1950s, are actively considering resettlement. Terry Hamilton is the Lab's Marshall Islands Program Director.

Hamilton:      Livermore became involved in about the mid 1970s to look at the level and distribution of fall out contamination. Since that time, we've been moving more towards resettlement support.  Our science has provided a basis for decision-making in terms of determining whether it's possible to resettle islands and atolls.

Narrator:       Their recommendations include limited soil removal around housing and village areas and adding potassium fertilizer to agricultural areas.

Hamilton:      The potassium treatment reduces the uptake of a common fission product from nuclear testing. So the combination of those two techniques we found is very effective.
