The world’s largest irradiator of Mo-99 targets

Complete supply chain in one location, unique in Europe


Europe’s only production process using low enriched uranium (LEU)

Which solutions does Mo-99 offer?

The isotope Mo-99 is an element used in the production of technetium-99m (Tc-99m). Tc-99m is used in research into a multitude of ailments. Roughly 85% of medical imaging in nuclear medicine uses this isotope (Tc-99m). Globally, this amounts to 17 million diagnostic procedures per year. Below is a selection of these.

Application of Mo-99

drag for more


Examining and imaging deviations in, for example, kidneys, lymph nodes, liver, gallbladder and other organs.

Cardiovascular diseases (cardiology)

Research into the blood flow of the heart muscle and the vascular system.

Bone examination

Investigating conditions that make the bone grow faster (locally). This could be metastasised cancer, but also bone fractures, inflammation or hormone-induced bone growth.


Production knowledge and engineering

We are the world leader regarding the irradiation of Mo-99 targets. These are aluminum plates containing low enriched uranium. During irradiation of these plates in the reactor, uranium is split by so-called fission, a process in which molybdenum-99 (Mo-99) is formed. Our customers then extract the Mo-99 from the targets with a chemical process. Ultimately, hospitals will receive so-called generators made from technetium-99m (Tc-99m), which is produced from Mo-99, an important raw material for medical research.

Furthermore, we have a unique infrastructure with logistical distribution points nearby. Our clients have an international nuclear pharmaceutical network with thousands of hospitals in about 100 countries. This is how medical isotopes produced in Petten find their way to 30.000 (cancer)patients every day.
