Hace 1 día · Antoine Henri Becquerel began his studies of radioactivity shortly after Wilhelm Conrad Rontgen's discovery of x-rays in 1895. Having already done extensive research into phosphorescence, Becquerel "began looking for a connection between [his research] and the newly discovered x-rays," utilizing uranium salts and other elements to conduct experiments on the emission of x-ray-like radiation in ...
