ACTIVELY ENHANCING LIVES AROUND THE WORLD 

NTP Radioisotopes is a leading global producer and supplier of nuclear medicine and radiation-based products and services.

NTP is a state-owned public company, and is a subsidiary of the South African Nuclear Energy Corporation (Necsa).

Originally conceived in the early 1970s to supply the local South African market with commercial radiopharmaceuticals, NTP is now among the world’s top producers and distributors of key medical radioisotope molybdenum-99 (Mo-99), and radioisotope-based diagnostic imaging and therapy products including iodine-131 and lutetium-177.
