He discovered that the cathode ray tube produces a high-powered radiation that can blacken the photo film. Furthermore, the rays are named X rays. X rays do not contain electrons, but are electromagnetic waves. X-rays are not deflected by the magnetic field, and have wavelengths shorter than the wavelength of light. Based on the results of the W.C Rontgen research, Henry Becquerel in 1896 intends to investigate X rays, but by chance he found symptoms of radioactivity. In his research he found that uranium salts can damage photo films even if sealed with black paper. According to Becquerel, this is because the uranium salts can emit a ray spontaneously. This event i called spontaneous activity radio Marie Curie was intrigued by Becquerel's findings, further with the help of her husband Piere C
