Vladimir Vysotskii presented his work in transmutation of Cesium 133 by anaerobic sea bacteria.
This is so fantastic that it deserve an independent post.
He explained first that Cesium, 133 and 137 were the most dangerous nuclear waste in fission, because of their biological characteristics.
Previously he observed some transmutations of cesium to barium , at rate allowing reduction by half in 200 to 500days.
the problem is that to decontaminate place like Fukushima you needed bacteria living in seawater.
He decided to use anaerobic methanogenic bacteria form the sea sludge.
His experiments was designed with 3 control experiments, without either the bacteria, the cesium, or the nutrient.
the result was amazing, and he observed 50% reduction of cesium in 8 days.
I thought about possible contamination by bottle, but we should not forget there are 3 control experiment that should be impacted by any artifact you imagine...
Another example of the quality of russian science, in LENR especially.
