Web9 jul. 2024 · For decay rates to be significantly faster in ancient times would require a much higher (&/or more energetic) neutrino flux in the past, which would imply that the reaction rate in the Sun's core was much faster in the past. But that doesn't make much sense: the Sun is gradually getting warmer, not cooler. WebThe rate of decay gives the number of nuclei that decay per second. Rate of Decay Formula is given as − d [ A] d t = k [ A] On integrating the above equation, we have l n [ A 0] [ A] = k t The half-life (t1/2) is given by t 1 / 2 = 0.693 k Example 1 The half-life of a 226-radium is 1622 years.
