Seaward ce­sium

Houston Chronicle Sunday - - WORLD -

Lev­els of ra­dioac­tive ce­sium have been found to be higher on Ja­panese beaches 60 miles from Fukushima’s melt­down-plagued nu­clear power plant than in sam­ples taken in the fa­cil­ity’s har­bor.

Sci­en­tists be­lieve the ce­sium-137 was car­ried by currents and ab­sorbed in dis­tant sandy beaches soon af­ter the 2011 nu­clear dis­as­ter.

Woods Hole Oceano­graphic In­sti­tu­tion re­searcher Ken Bues­seler says the sand acted as a sponge that soaked up the con­tam­i­na­tion, which is be­ing slowly de­pleted.
