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

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

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.
