<p>A method of decontaminating the surface of a body carrying radioactive contaminants which comprises treating the surface with a decontaminant comprising a solution of tetrafluoroboric acid HBF4, treating the resultant liquor comprising decontaminant and dissolved species removed from the body surface with a first chemical agent which on reacting with the dissolved species yields insoluble compounds and regenerated decontaminant solution, and characterised in that the regenerated decontaminant solution is further treated to cause removal of the first chemical agent from the decontaminant solution.</p> |
