phosphates,rare earths and elements from the radioactive portion of the table of elemants can be found associated with other in nature.
as far as making the countryside radioactive from fertiliser goes, i suggest taking an envelope,multiplying the radioactive content of fertiliser by the application rate per acre,dividing it by the weight of the top few meters of the area of farmland that is fertilised, then havin a nice hot cup of tea and a good lie down.
granite is naturally radioactive, and when it comes to productive,clean farmland,some of the granite soils are as good as it gets.
what next, the abc runs an expose calling for the banning of fertiliser? just pick the 4 billion people that you want to die off, and we can go back to sewerage to make your leafy vegetables grow.
