Question

how to kill cancer cell by isotopes?

Answer 1

Radioisotopes, or radionuclides, are particles that emit energy. Some of these particles (alpha and beta particles) emit damaging radiation that can be attached to carrier molecules to directly target cancer cells within the bloodstream.

Yttrium-90 is used for treatment of cancer, particularly non-Hodgkin's lymphoma and liver cancer, and it is being used more widely, including for arthritis treatment. Lu-177 and Y-90 are becoming the main RNT agents. Iodine-131, samarium-153, and phosphorus-32 are also used for therapy.
