[en] An extensive historical study over the legacies of the raw phosphate processing in Germany revealed a consumption of approx. 150 million tons raw phosphates with an own production of approx. 1 million tons. This corresponds to approx. 222 million MBq U-238. The production of elemental phosphorus amounted to approx. 3 million tons (slag: 36 million MBq Ra-226) and of phosphoric acid to approx. 12 million tons (phosphogypsum: 27 million MBq Ra-226). In this way, the basis for finding concrete legacies and their radiological evaluation (measurements, exposure assessment) has been created. (author)
