Paris stayed cloudy in late February 1896, so he put plates wrapped in black paper, with uranium salt on top, in a drawer. On 1 March he developed them anyway and found strong images: the uranium emitted penetrating rays with no sunlight at all (Comptes rendus 122, 501, 1896). It was radioactivity.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003euranium → rays, no light needed\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003euranium salt: potassium uranyl sulfate in his first tests\u003c\/li\u003e\n\u003cli\u003eplate: photographic plate wrapped in black paper\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eMarie and Pierre Curie took up the work, named radioactivity and found polonium and radium.
