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.
