How would CS-137 be present in coal ash slurry? 1950's legacy contamination from Oak Ridge? Any samples/ in situ readings would probably have thorium and radium d/p's.  But no mention of that in the article.
Cost concerns have Oak Ridge using 1960's scalers instead of gamma spec?
Don't ask the question if you don't want the answer?
