Whose law explains radioactivity decay?
SciencePhysics
Quick Answer
Henri Becquerel discovered radioactivity, but the decay law is most closely associated with Ernest Rutherford and Frederick Soddy. Their work showed radioactive substances decrease at a predictable exponential rate.
The Full Story
The law of radioactive decay is associated with Ernest Rutherford and Frederick Soddy, who explained in 1902 that radioactive atoms transform at a characteristic rate. This was one of the foundations of nuclear physics. Becquerel discovered radioactivity in 1896, but Rutherford and Soddy provided the quantitative law behind it. Their work helped establish the concept of half-life, now used in medicine, archaeology, and nuclear science.
