Answer: Alpha emission, beta emission, postitron emission,electron capture and gamma emission.
Step-by-step explanation:
A=- \frac {dN}{dt}Another important atomic clock used for dating purposes is based on the radioactive decay of the isotope carbon-14 As an example, iodine-131 is a radioisotope with a half-life of 8 days. It decays by beta particle emission into xenon-131. After eight days have passed, half of the atoms of any sample of iodine-131 will have decayed, and the sample will now be 50% iodine-131 and 50% xenon-131.
