2 de may. de 2024 · Between 1902 and 1903 physicists Ernest Rutherford and Frederick Soddy together proposed that each type of radioactive element decays at a unique and unvarying rate. This is the concept of the radioactive half-life.
2 de may. de 2024 · By 1911 Frederick Soddy discovered that naturally-radioactive elements had a number of different isotopes (radionuclides), with the same chemistry. Also in 1911, George de Hevesy showed that such radionuclides were invaluable as tracers, because minute amounts could readily be detected with simple instruments.
