Radiochemical analyses

Our offer

Many companies, including nuclear power plant operators, producers of medical radioisotopes, radioactive waste processors and nuclear research installations ask us to conduct chemical and radiochemical analyses on their behalf.

The Radiochemistry (RCA) expert group can determine the chemical and radiochemical composition, the activity of radionuclides (alpha, beta and gamma activities), and quantify trace elements and chemical impurities in both aqueous solutions (leach waters, reactor cooling waters, waste waters, etc.) and solid matter (radioactive waste, unirradiated and spent nuclear fuels, resins, filters, soil samples, etc.).

We have access to a wide range of analytical equipment and radiochemical laboratories for the analysis of both low- and high-level radioactive samples. Our laboratories are equipped with fume hoods, glove boxes and hot cells. Our extensive experience built up over many years enables us to determine the chemical and radiochemical composition of even the most complex materials and samples.

If needed, and especially for complex samples, we can apply specific sample preparation techniques (combustion, microwave and high-pressure digestion, etc.) and radiochemical separations to a sample.

Our equipment

The following analytical techniques are used for the chemical and radiochemical analysis of different nuclear materials:

  • Alpha and gamma spectrometry
  • Liquid scintillation counting (LSC)
  • Atomic spectrometry (ICP-AES)
  • Chromatography (HPLC, IC)
  • Mass spectrometry (ICP-MS, HR-ICP-MS, TIMS)
  • Elemental analysis (O/N/H combustion analysis)
  • Total carbon analysis (TIC/TOC)

The RCA expert group also manages complex facilities including

  • Radiochemical laboratories
  • Chains of glove boxes
  • Lead-shielded cells

all of which together enable the treatment and analysis of low- to high-level radioactive samples.

Quality Assurance

Many of our radiochemical analytical methods are certified according to ISO 17025. In addition, we participate on a regular basis to interlaboratory comparison exercises and proficiency tests to verify and assess the quality of our analytical methods.
