FAQ
Frequently Asked Questions
No, but the vast majority are. A small number of stable isotopes are also produced as fission products.
They are radioactive waste. Their management, containment, and long-term storage pose significant technical and environmental challenges.
Not exactly. Fission products are a major *component* of high-level nuclear waste, but the waste also includes other materials like activated structural components and unused fuel.
Yes, some have industrial or medical applications. For example, Strontium-90 is used in radioisotope thermoelectric generators (RTGs) for spacecraft, and Technetium-99m is a vital medical tracer.
