he noticed the first effects of radioactivity while he observed that with exposure to the sunlight the mineral gave off a penetrating energy that could expose film.
He found out that uranium salts caused fogging of an unexposed photographic plate. :)

Henri Becquerel discovered radioactivity, together with the famous Marie Curie. The word "Becquerel" is now used as an S.I. unit of radioactivity. 1 Becquerel (Bq) means that 1 nucleus decays each second.
Radioactivity was first discovered by Henri Becquerel on the 1890s. He received the Nobel Prize, along with the Curie's, for this work.
Henri Becquerel discovered in 1896 the natural radioactivity of uranium.
Radioactivity was discovered by Henry Becquerel but the term 'Radioactivity' was given by Madam Curie. It is the process of process of spontaneous disintegration of nucleus and is measured by Geiger counter.
