\r\n\r\n\r\n\r\nSeven different mixtures of radionuclides for calibrating high resolution gamma-ray spectrometers are offered. The radionuclides are recommended by NIST (USA) and 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 UK.\r\n\r\nTo ensure the highest accuracy and consistency possible, each radionuclide in the mixture is individually assayed. The mixed solutions are prepared by gravimetric dispensing and then checked by high resolution gamma-ray spectrometry. For high sensitivity, gamma-ray emitting impurities are determined by high resolution gamma-ray spectroscopy of each individual radionuclide in the mixture. Some radionuclides are also checked by radiochemical analysis. The final mixture is then checked for cross-contamination.\r\n\r\nIn addition to the principal gamma rays shown on the certificate of calibration, several low intensity photopeaks may be observed in the spectrum. The most significant are shown in the table below.\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n

7500 and 7600 Nuclide Mixtures<\/h3>\r\n\r\n
\r\n\r\nThe 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.\r\n\r\nTwo nine-nuclide gamma standards are offered:\r\n- Series 7500 contains Te-123m and Cr-51 for those customers who require a non-mercury containing standard.\r\n- Series 7600 contains Hg-203 and Ce-139.\r\n\r\nPlease 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 sources are calibrated, traceable to NIST or with DAkkS certificate. They are prepared gravimetrically from calibrated solutions and then confirmed using a high purity germanium detector to ensure the highest possible quality.\r\n\r\n \r\n\r\n\r\n\r\n<\/div>\r\n\r\n\r\n<\/div>\r\n
