Applying for the transfer of radioactive isotopes must meet the following requirements:
(1) The transfer-out and transfer-in units hold licenses consistent with the activities they are engaged in;
(2) The transferring unit has a disposal plan for the radioactive isotope after its use period expires;
(3) Both parties to the transfer have signed a written transfer agreement.
If two atoms have the same number of protons but different numbers of neutrons, they still have the same atomic number and are elements at the same position in the periodic table, so they are called isotopes. Radioactive isotopes are called "radioactive isotopes"
