Petit fragment d'autinite Ca(UO2)2(PO4)2 · 10-12H2O. Minéral d'uranium (radioactif ! ) du Portugal (qui crache bien au compteur Geiger !) 

Belle cristallisation cubique indiquant +400 coups par minute au compteur Geiger ... (j'ai stoppé les mesures en raison des plaintes de ma fille...!) et superbe fluorescence sous UV long (comme vous pouvez le voir ...)  

Collection : Minéraux
