EMRP project MetroMetal: selected results of ENVINET and CMI.

Within the framework of the European Metrological Research Program (EMRP) IND04 MetroMetal 'Ionizing radiation metrology for the metallurgical industry', joint research carried out by 14 metrological institutions from countries within the European Union and the company ENVINET, questions concerning the determination of radioactivity in samples relevant to the metallurgical industry were resolved. The results of project tasks, namely questionnaire, composite standards development and samples from metallurgical industry measurement, are presented here.

[Drug-induced fluorosis].

Report of a 58 year old patient who, after a 5 year continuous treatment with altogether 146 g sodium fluoride, developed a grade II-III (Roholm) fluorosis. The fluorine treatment had been conducted for a radiologically demonstrated osteoporosis. Renal involvement was not demonstrated: serum creatinine was normal, the creatinine clearance only slightly reduced.
