Radiometry Specialist (P3)

IAEA - International Atomic Energy Agency

Seibersdorf, Austria

Main Purpose

The Radiometry Specialist is an expert in laboratory based non-destructive analysis (NDA) instrumentation applied to the actinides, and is the technical lead for the advancement of the hybrid K-Edge densitometry technology (HKED) as it is currently applied by the IAEA at the On-Site Laboratory (OSL) in Japan. The Radiometry Specialist also backs up the Radiometry Team Leader in case of absence.


The Radiometry Specialist is: (1) a non-destructive assay analyst, performing measurements using a variety of NDA systems, analyzing and interpreting measured data and preparing reports; (2) a technical specialist in HKED that interfaces with technical staff, regulators, and Safeguards organizations to understand operational needs for the measurement of actinide process samples.

Functions / Key Results Expected

  • Lead HKED improvements in hardware optimization and upgrades, software updates and training, and method development to support evolving sample measurement challenges.
  • Advise on the development of new HKED software data processing and interpretation.
  • Maintain an in-depth technical knowledge of radiometric systems and techniques including alpha and gamma spectrometry, and X-Ray fluorescence. Advise the Radiometry Team Leader on enhancements or issues with current systems.
  • Provide technical expertise in the analysis of several hundred nuclear material samples per year and ensure that data are reported within established quality and timeliness goals for each type of analysis.
  • Maintain up-to-date knowledge in the radiometry field by attending scientific meetings and by communicating with instrument vendors and colleagues outside the IAEA working in related fields.

The incumbent may perform his/her work in areas involving exposure to radioactive materials. Therefore, as an Occupationally Exposed Worker, he/she must be medically cleared by VIC Medical Service and is subject to an appropriate radiation and health monitoring programme, in accordance with the IAEA's Radiation Safety Regulations.
