Researchers at Kinki University said May 23 they have developed plaster for use in home construction that is capable of absorbing radioactive cesium.
The team led by Tsuyoshi Morimura, a former professor of the university’s faculty of engineering, produced the plaster by blending in zeolite, a microporous mineral capable of soaking up cesium.
The plaster removed 99 percent or more of cesium when the team filtered a cesium-water solution with the material.
Hopes are high that the plaster will be used at facilities to store cesium-tainted substances generated by the nuclear disaster in Fukushima Prefecture last year.
Plaster is often applied to walls and floors in home construction.
