New technology can remove 99.9 percent of radioactive cesium in soil

The method employs a small rotating furnace, in which cesium-tainted soil is mixed with calcium compounds to promote a reaction before the materials are heated at 1,350 degrees Celsius. The cesium separated from the tainted soil is then captured by filters.

When tested on contaminated soil in Fukushima Prefecture, the levels of radioactive cesium in the soil decreased from 67,300 becquerels per kilogram to 29 becquerels. Although the filters, tainted with cesium after the process, need careful handling, the method is expected to contribute to reducing the amount of radioactive waste.

That is great. Now if they could do that with the atmosphere...
