The IAEA continues to provide credible assurance to the international community regarding States’ adherences to their safeguards obligations under the nuclear NonProliferation Treaty. Generally, industrial activities, including those related to the nuclear fuel cycle, are operating on increasingly larger scales involving more equipment, more nuclear material products and flows. With limited res...

Models commonly used in tritium dose assessment are steady state specificactivity models based on the assumption of complete isotopic mixing with the stable element, and isotopic equilibrium between all environmental compartments (IAEA, 2010). These models may not be adapted to situations with fluctuating tritium levels in rivers, resulting from discontinuous radioactive discharges or accidenta...

Patients entering hospitals in the USA are reported to have about one chance in three of having a radioactive tracer play a role in the diagnosis of their medical problem. , One important diagnostic technique is radionuclide imaging — the use of radioactive isotopes to obtain images of body organs and processes. The IAEA, from its very beginning, has paid close attention to this particular fiel...

In the burning fusion plasmas of next step devices such as ITER (2001 ITERFEAT Outline Design Report IAEA/ITER EDA/DS/18 (Vienna: IAEA) p 21), the majority of the heating of the fusing fuel will come from the plasma self-heating by fusion born α-particles. Recent advances in theoretical understanding, together with the development of new diagnostic techniques, make this a timely opportunity to ...
