7500 and 7600 Type

The 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. IPL offers two nine-nuclide gamma standards. 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 multinuclide 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.

Multinuclide standards are made to order and are available on a year-round basis in a variety of configurations. Standards can be supplied for special applications with nuclides, activities, containers and matrices manufactured to customer specifications.

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.

8400, 8500 and 8600 Type

The mixed nuclide gamma standards, routinely used to establish efficiency curves for gamma spectrometers, cover an energy range from 88 keV to 1836 keV.  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.  The mixtures minimize coincident summing effects, which is particularly important when counting close to large, high-efficiency, germanium detectors.

Three mixed nuclide gamma standards are offered.

-    Series 8400 contains Hg-203.
-    Series 8500 contains Hg-203 and adds Sr-85
-    For those customers who require a non-mercury containing standard, Series 8600 replaces Hg-203 with Cr-51 and adds Sr-85.

These mixed nuclide standards are NIST traceable with each component certified with an uncertainty less than ± 5% at the 95% confidence level.  The mixed nuclide standards are prepared gravimetrically from calibrated solutions and then confirmed using a high purity germanium detector to ensure the highest possible quality.

As options, Am-241 and/or Pb-210 can be added to extend the calibration curve down to 60 keV and 46 keV respectively.  In order to measure coincidence-summing effects Mn-54 and/or Zn-65 can also be added upon request.

8700 Type - True Coincidence Correction Mixture (TCC)

The True Coincidence Correction (TCC) mixture is used with special software to correct for coincidence summing effects.  As an option, Pb-210 can be added to extend the calibration curve down to 46 keV.

The TCC mixed nuclide standards are NIST traceable with each component certified with an uncertainty less than ± 5% at the 95% confidence level.  The mixed nuclide standards are prepared gravimetrically from calibrated solutions and then confirmed using a high purity germanium detector to ensure the highest possible quality.
