Answer :
The radioactive isotopes of oxygen are O-13 and O-14.
Isotopes are the variations of differences in the atoms which are classified as belonging to the same element. An element is determined by the proton numbers in nucleus, therefore all isotopes of same element will have same protons number and different neutrons number.
Radioactive isotopes are also called as radioisotope. These are the forms of elements which are unstable and emits the radiations so that they can be transformed into a form which is more stable.
O-15 or Oxygen-15 is also a radioisotope which is used in the positron emission tomography (PET). Oxygen has several radioactive isotopes, each used for different purpose in different fields. O-14 is radiogenic, it is produced by the decay of the other atoms. O-14 is also a positron emitter
O-13 and O-14 undergoes the electron capture for their nuclear decays and they have short half lives of about 100 seconds.
