The incorrect statement is: "P-33 is used in the treatment of Leukemia." Phosphorus-33 is not a standard medical radioisotope. The correct isotope used for leukemia treatment is phosphorus-32 ( ${}^{32}P_{15}$ ), which is a beta emitter.

Cobalt-60, not Co-59, is used in cancer radiotherapy. Excessive radiation exposure is a known carcinogen, and Iodine-131 is indeed used for thyroid disorders.

Final Answer: P-33 is used in the treatment of Leukemia.
