While in prison, he suffered a heart attack and died on December 30, 1947.
Thus, if denotes the number of atoms present at time t, then equation I The constant which is positive is known as the decay constant of the substance.
The larger is, of course, the faster the substance decays.
The physicist Rutherford and his colleagues showed that the atoms of certain “radioactive” elements are unstable and that within a given time period a fixed proportion of the atoms spontaneously disintegrates to form atoms of a new element.
Because radioactivity is a property of the atom, Rutherford showed that the radioactivity of a substance is directly proportional to the number of atoms of the substance present.
