7500- and 7600 Type

The mixed nine-nuclide gamma standard, routinely used to establish efficiency curves for gamma spectrometers, covers an energy range from 88 keV to 1836 keV. As options, Am-241 and/ or Pb-210 can be added to extend the calibration curve down to 60 keV and 46 keV respectively. Two nine-nuclide gamma standards are offered. Series 7500 contains Te-123m and Cr-51 for those customers who require a non-mercury containing standard.Series 7600 contains Hg-203 and Ce-139. Please note that Hg-203 may leach out from polyethylene containers and may contaminate the entire container. Proper handling techniques must be observed. The component nuclides of each series have been chosen to minimize peak interference, and the activity ratios have been selected to yield similar count rates in all major peaks on typical coaxial germanium detectors.These mixed nuclide standards are NIST traceable with each component certified with an uncertainty less than ± 5% at the 99% confidence level except for Pb-210 when added. The multinuclide standards are prepared gravimetrically from calibrated solutions and then confirmed using a high purity germanium detector to ensure the highest possible quality.

NG1 and NG4 – QCYB-Type

These nuclide mixtures are recommended by PTB (Germany) and cover the energy range 46-1836keV. The solutions are calibrated in our DAkkS accredited measurement laboratory and are traceable to national standards world-wide, including the USA, France, Germany and the United Kingdom.

*)Nuclide mixture 1 (NG1): The half lives of the component radio­nuclides are relatively long(shortest is 65 days, Sr-85). At close source-detector distances, summation effects become important.

**)Nuclide mixture 4 (NG4): Intended for low energy calibration only.

NPL solutions for environmental measurements

Uncertainties

The reported uncertainty is based on a standard uncertainty multiplied by a coverage factor k=2, providing a level of confidence of approximately 95%.

Traceability

The solutions are directly traceable to the United Kingdoms absolute primary radioactivity standards. NPL regularly participates in validation and calibration exercises with other national standards laboratories organized under the auspices of the International Bureau for Weights and Measures (BIPM).Via this route and the Mutual Recognition Arrangement, traceability to NPL is accepted as attributing traceability to other national standards laboratories in many other countries, eg. NIST (USA), LNHB (France) and PTB (Germany).

Quality assurance

NPL Management Ltd has been approved by Lloyds Register Quality Assurance Ltd for certification to ISO9001:2000. The provision of NPL’s environmental standards has been accredited by UKAS to ISO17025:1999.Availability (lead time)

The solutions are dispatched within two weeks of receipt of order, or within two weeks of receipt of export license if required.
