SCK CEN lives up to promises of international summit in The Hague

The medical sector has always been able to rely on the nuclear research centre SCK CEN. It produces sorely needed medical radioisotopes in its BR2 research reactor, including molybdenum-99 and iodine-131. The former can be used to detect cancer and cardiovascular diseases. The latter, radioactive iodine, is in turn used to fight thyroid cancer. Both radioisotopes are created by irradiating uranium targets – tubes about 16 centimetres long. After 51 years, SCK CEN is switching completely to low-enriched uranium as base material. "Nothing changes for the patient or doctor, but it does for the world," said Steven Van Dyck, BR2 director. And he means that from a non-proliferation perspective. Since highly enriched uranium is no longer used in the production of these medical radioisotopes, that nips a potential spread of it in the bud.
