Suppression methods of radon emanation from phosphorus fertiliser and diatomaceous earth.

abstract：:New imaging technologies utilising X rays and radiopharmaceuticals are continuously under development. The benefit of computed tomography (CT) has been so dramatic that there is a tendency to overuse it and not to place enough efforts into optimisation of the technique. It is also now more and more common to combine t...
