Each “E”-vial reference source comes with a certificate of radioactivity calibration that guarantees accuracy within 5%. The critical nature of NRC and Agreement State regulations for dose calibrator QC demand the most accurate reference sources available.

Reference sources can be purchased individually, or in cost-effective sets of three or four. Sets come in various combinations of radionuclide sources to fit your needs. An 18-month day-to-day decay calendar is available to eliminate calculations.

If you need a reference source with an activity not listed in this catalog, Capintec can meet your special request promptly. Capintec will arrange for disposal of the original source with purchase of a replacement source.
