Single-Radionuclide Standards

Calibrations utilizing Analytics' standards have demonstrated traceability to NIST. Analytics participation in the NIST/ Nuclear Energy Institute (NIST/NEI) Measurements Assurance Program for the Nuclear Power Industry satisfies the requirements of the United States' Nuclear Regulatory Commission's Regulatory Guide 4.15, Revision 1, 1979 and ANSI N42.22-1995 American National Standard - Traceability of Radioactive Sources to the National Institute of Standards and Technology (NIST) and Associated Instrument Quality Control.

Analytics can prepare custom-geometry single-radionuclide standards utilizing a wide variety of radionuclides. Contact us with your specifications of radionuclide, activity and geometry. All custom-made, calibration standards must pass Analytics' documented quality-control requirements.

Matrices

Over the past twenty-five years Analytics has prepared custom-made standards in hundreds of different geometries utilizing many different matrices.

  • Water-equivalent solid standards are prepared in hundreds of different geometries. These standards are individually traceable and much safer to handle in the counting room than liquid standards. There is no possibility of leakage, spillage or plate-out of the radioactive material. Matrix density is 1.15 g/cc.
  • Air Filter standards are uniformly deposited to your specifications and sealed in customer supplied counting configurations.
  • Charcoal and silver zeolite cartridge standards are prepared in your cartridges loaded to your specifications.
  • Soil or sand standards are prepared in customer supplied counting containers. Matrix density range from 1.5 g/cc to 1.7 g/cc.
  • High density solids with density range from 1.5 to 2.0 g/cc.
  • Vegetation or simulated vegetation standards are prepared in customer supplied counting containers with an approximate density of 0.6 g/cc.
  • Simulated gas standards are prepared in customer supplied gas counting containers. These low-density (0.02 g/cc) standards have the same gamma-ray attenuation characteristics as actual gas standards and greatly extend the energy range and useful life of the calibration standard.
  • Point sources are mounted in various geometries, again to your specifications.

If you do not find your specific geometry give us a call. Let us put our experience in preparing custom standards to work for you.

Each standard is prepared gravimetrically with a calibrated balance. After preparation, each standard is counted with a calibrated detector system.
