radioactivity

One of the big stumbling blocks when it comes to properly handling North Dakota’s substantial tonnage of radioactive wastes has been the time it takes for an accurate test of how much Radium 226 and 228 are present in a given load of the material.

Scientists have developed oxidized carbon particles that extract radioactive metals, such as cesium and strontium, from water. They said the materials may help purify contaminated waters stored after the Fukushima nuclear power plant accident and also can trap common radioactive elements found in waterfloods from oil extraction, such as uranium, thorium, and radium,
