What are the differences between radiography, radiation therapy, and nuclear medicine?

Diagnosis vs therapy: Radiation therapy uses high-energy xrays to kill cancer cells or other types of growths in the body, for therapeutic purposes. Radiology uses lower-energy xrays to view the inside of the body, for diagnostic purposes. Nuclear medicine uses the injection of radioactive material into the body either to view "active" areas within the body (diagnostic) or to kill malignant cells (therapuetic). Thanks.

Different radiation: Radiography or x-ray involves low dose ionizing radiation with images of chest , skeleton, skull etc. Radiation therapy uses high dose ionizing to treat tumors with external or internal irradiation. Nuclear medicine involves low dose ionizing radiation in form of isotopes that are internally injected intravenously. Inhaled, injected subcutaneously, or ingested orally.
