2240 IRRADIATED PERSONAL DOSEMETERS FOR THE IC2014 EURADOS INTERCOMPARISON AT SEIBERSDORF

Area of Science:

• Medical Physics
• Radiation Dosimetry
• Nuclear Engineering

Background:

• The IC2014 EURADOS intercomparison is crucial for validating individual monitoring systems.
• Accurate dosimetry is essential for radiation protection and regulatory compliance.
• The Dosimetry Laboratory Seibersdorf has a key role in such intercomparisons.

Purpose of the Study:

• To serve as the irradiation laboratory for the IC2014 EURADOS intercomparison.
• To irradiate a large number of personal dosemeters under controlled conditions.
• To assess the performance of whole-body dosimetry systems in terms of personal dose equivalent.

Main Methods:

• Irradiation of 2240 personal dosemeters from 112 dosimetry systems.
• Use of ISO water slab phantom for simulating human exposure.
• Irradiation with photon reference fields including Cs-137, Co-60, and 320-kV X-rays.
• Employing nine irradiation setups with five ISO/IEC photon radiation qualities and two angles of incidence (0° and 60°).

Main Results:

• Reference dose equivalent values ranged from approximately 1 to 500 mSv.
• Reference values were established using air kerma rate traceable to primary standards.
• Total expanded measurement uncertainties for reference values were less than 6%.

Conclusions:

• The Dosimetry Laboratory Seibersdorf successfully conducted the irradiation phase of the IC2014 EURADOS intercomparison.
• The established reference dosimetry provided a reliable basis for evaluating participating dosimetry systems.
• The results contribute to the overall quality assurance of individual monitoring in Europe.
