Nuclear radiation protection

Guarantee radioactive materials are handled and disposed of safely

What is nuclear radiation protection and why is it important?

Radiation protection is the means for ensuring the safety of people from the harmful effects of exposure to ionizing radiation. In nuclear power plants, it is important to prove that all radioactive materials are handled safely. Your installation has to comply with all regulations and standards for the licensing procedure. In addition, your materials and electronic devices must remain operable when exposed to radiation.

 

TÜV SÜD ensures that your radioactive materials are handled and disposed of safely

Our expertise ensures optimum protection from ionising radiation, effective disposal of radioactive waste and safe dismantling of nuclear facilities at the end of their lifecycle. Beyond measuring radioactivity, our experts support you in the handling of radioactive materials and activity flow. We can also assist you with occupational radiation protection such as shielding calculations, dose measurements and inspections according to the ALARA principle. A filter test laboratory based in Germany provides multiple test methods for determining the retention efficiency of iodine filters and the performance index of activated carbon. This is valuable for operators of nuclear power plant or iodine therapy station as well as manufacturers of active carbon or respiratory filters.

 

What does nuclear radiation protection involve?

Radioactivity measurement

  • Assistance in radiation and activity monitoring in nuclear facilities, from conceptual design to support during implementation and maintenance
  • Measurement of radioactivity on site and in accredited radiation laboratories
  • Leakage tests of radioactive sources
  • Testing of accelerators

 

Radioactive materials, activity flow and radioecology

  • Evaluation of activity flow, activity retention and confinement of radioactive materials
  • Dispersion analysis of radioactive substances in air and water
  • Radiological incident analysis, comprising identification and evaluation of accidents as well as evaluation of the release and dispersion of radioactive materials
  • Assistance with radiation protection issues in a radiological emergency
  • Determination of radiation exposure for airborne and liquid discharges as well as naturally occurring radioactive materials (NORM/ TENORM)
  • Environmental impact assessments (EIA)

 

Occupational radiation protection

  • Assessment of structural, technical and administrative radiation protection measures and organization
  • Advisory on external and internal radiation exposure control and shielding design
  • Optimisation with recognised computer codes
  • Determination of radiation resistance of materials and electronic devices to guarantee they operate when exposed to radiation

 

FILTER TEST LABORATORY AND FILTER TESTING ON-SITE ACCREDITED ACCORDING TO DIN EN ISO/IEC 17025:2018

  • Check of retention efficiency of iodine filters
  • Laboratory tests of filter efficiency and performance index of the used materials
  • On-site testing of aerosol filters with uranine testing equipment according to DIN EN ISO 16170
  • On-site inspections of Iodine filter systems

 

FILTER LABORATORY “PANDUR”

  • Tests of sorption materials of iodine filters under normal conditions
  • Control samples from nuclear power plants (according to KTA 3601 or ASTM D3803)
  • Performance index (K-value) of new/unused activated carbon from carbon suppliers or from nuclear power plants’ stocks
  • Tests using radioactively marked methyl iodide as test medium
  • Temperatures between 23˚C and 35˚C, air humidity until 95% r.F.
  • Tests of respiratory filters according to DIN 58621

 

FILTER LABORATORY “HIGH TEMPERATURE DEVICE (HTA)”

  • Tests of sorption materials from iodine filters under failure or accident conditions
  • Up to 160˚C and a variable mixture of steam and air, using radioactively marked methyl iodide as test medium
