For instance, a number of radioactive atoms shot through a tube at high speed in the lab will have their half-life lengthened relative to the lab because of time dilation. Traveling at a speed close to the speed of light causes time to slow down significantly, relative to the stationary observer. Everything that experiences time can therefore be given a longer effective lifetime if time is dilated. According to relativity, time itself can be slowed down. The half-life of a radioactive material can be changed using time dilation effects. Rather, the half-life describes the average amount of time it takes for a large group of atoms to reach the point where half of the atoms have decayed. The half-life of a certain type of atom does not describe the exact amount of time that every single atom experiences before decaying. It is impossible to predict when an individual radioactive atom will decay. However, this statement is not completely true.įirst of all, it is worth pointing out that the time when an individual radioactive atom decays is completely random. Since radioactive decay is a spontaneous event, you may think that the half-life of the decay process is completely fixed and cannot be altered by outside influences. This process changes the atom to a different element or a different isotope. Radioactive decay happens when an unstable atomic nucleus spontaneously changes to a lower-energy state and spits out a bit of radiation. Yes, the decay half-life of a radioactive material can be changed. Public Domain Image, source: Christopher S.
