Accredited Laboratories

Our accredited laboratories are active in the five areas of mechanical, physicochemical, electrical, radiation and radiochemical (radioactivity) material properties, as well as in accredited measurements, tests, and analyses. The laboratories are awarded accreditation certificates by the ČIA, o.p.s. (National Accreditation Body) following regular verifications of compliance with the accreditation criteria according to ISO/IEC 17025.

In the field of measurement and radiochemical analyses we provide the following services:

  • Accredited determination of radionuclide content in different materials and media
  • Detection and determination of the content of nuclear materials
  • Characterization of radioactive waste
  • Determining the biomass content (share) of fuels
  • Radiation monitoring of workplaces and the environment
  • Determination of toxic metal content in different materials and media
  • Measurement of the effectiveness of air-conditioning, aerosol and iodine filters.

Important analyses are performed by accredited methods within the Central Analytical Laboratory - Testing Laboratory (CAL-ZL). This is the determination and monitoring of radionuclides important for the safe operation of nuclear installations; Determination and monitoring of radioactive, toxic and other isotopes relevant for environmental protection, and samples of natural materials, analysis of gas and biomass samples.
