Calibrated Solid Sources

Safe, calibrated solid sealed sources are fabricated by depositing a license exempt quantity of activity in the well of a 2-inch diameter (50mm) by 1/8-inch thick (3mm) plastic disk. After drying, the well is filled with an epoxy material; sealing the radioactivity inside the source. Calibrations are ±5% and are performed using a high-purity germanium detector for which peak efficiencies have been established using a NIST traceable standard. Each disk is identified by radionuclide, amount of activity, serial number and calibration date. The words "Caution - Radioactive Material" appear on the label of each source.

Sources are available in stock at an activity of ~1.0 microcurie. They may be ordered individually or as a set. Sources are available at other activities within the ranges listed below for a nominal charge. When ordering, please indicate any special activity requirements.

Solid Calibration Point Sources

2" diameter, 0.125" thick acrylic disks. Calibrated gamma standards. License exempt.

Custom sources containing the above nuclides at activities outside of the ranges listed above and not exceeding exempt quantities may be quoted upon request.
