A pilot study was performed to verify the troubles involved in the implementation of dosimetric protocol TRS 398 for absorbed-dose-to-water, using clinical high-energy electron beams and to accomplish an detailed evaluation of uncertainty chain components associated to the measurement, which ones were not treated in the IAEA protocols, aimed the standardization of technical procedures.

Nuclear power plants alone are not a proliferation risk. Without enrichment or reprocessing capabilities, power-reactor fuel, whether fresh or spent, cannot be used for the production of nuclear weapons. There are various ways, however, in which reactor projects and related nuclear fuel-cycle facilities could be used to further a nuclear-weapons development programme. This chapter describes the...

Installed throughout a nuclear power plant, instrumentation and control (I&C) is an essential element in the normal, abnormal and emergency operation of nuclear power plants (International Atomic Energy Agency [IAEA], n.d.). Through their equipment, modules, sensors, and transmitters, I&C systems measure thousands of variables and processes the data to activate pumps, valves, motors, and other ...

A rapid continuous-Ñow technique for the quantitative determination of hydrogen isotope ratios in organic materials and water, at natural abundance levels, is described. Samples are pyrolysed in a helium stream at 1080 ÄC over an inert form of carbon. Hydrogen is separated from the other pyrolysis gases by gas chromatography and enters the ion source of the isotope ratio mass spectrometer (IRMS...

PURPOSE The objectives of the study were to use the International Atomic Energy Agency (IAEA) software package for the analysis of scintigraphic renal dynamic studies to obtain values of curve parameters and excretory parameters in children with hydronephrosis and to validate the reliability of these numerical outputs by comparing with values established by consensus reports. PATIENTS AND MET...

With the increasing tendency of natural hazards, the typhoon/hurricane/tropical cyclone induced surge, wave, precipitation and river flood as extreme external loads not only menace Nuclear Power Plants (NPP) in coastal areas, but also some inland territorial NPP. For all of planned, designed and constructed NPP the National Nuclear Safety Administration of China and International Atomic Energy ...

UNLABELLED The International Atomic Energy Agency (IAEA) has a long tradition of supporting development of methodologies for national networks providing quality audits in radiotherapy. A series of co-ordinated research projects (CRPs) has been conducted by the IAEA since 1995 assisting national external audit groups developing national audit programs. The CRP 'Development of Quality Audits for ...
