This is important to know to avoid a hysterical reaction when you read a media report of a large number of becquerels associated with the Fukushima disaster. Becquerel, of course, found that the plates were fogged by the uranium crystal and that "activation" by the sunlight was not needed. The units used to measure radioactivity are becquerel (Bq) and curie (Ci). The SI-derived unit of radioactivity is the becquerel (Bq). Radioactivity was discovered by the French scientist Antoine Henri Becquerel in 1986 practically by chance, while he researched the fluorescence of double uranium and potassium sulphate. He was 55 years old. The values of dose factors, which convert ‘activities’ in becquerels to ‘doses’ in sieverts, are very tiny because the Sievert (Sv) is a large unit and the Becquerel(Bq) a very small one. Fraser Cain: So, Antoine Henri Becquerel discovered radioactivity completely by accident when he exposed a chunk of uranium to a photographic plate. A nucleus that spontaneously destroys part of its mass to emit radiation is undergoing radioactive decay. Welcome to OnlineConversion.com. Children with more than 60 becquerels of radioactivity per kilo of bodyweight are thought to be at risk from disease. X-rays are neutral and cannot be bent in a magnetic field. Elsewhere, M.
