MS maps actinides in exposed workers

摘要

To understand and quantify human exponsure to radioactive elements, scientistsnhave traditionally faced a conundrum:nmethods that would allow them to visual-nize radioactive distribution within tissuenhave not allowed them to simultaneouslynpinpoint the identities and concentrationsnof the elements involved. An autoradio-ngraph shows a visual distribution of alphanparticle decay but does not reveal thenidentity of the element causing it. Radio-nchemical methods identify and quantifynelements by dissolving the sample, but thneliminates information about the distribu-ntion of the elements.
