Rod and Disk Sources provide a safe and convenient method of calibration and quality control of scintillation detectors and well counters. Many Rod Sources are NIST traceable within ±5% at the 99% confidence level. Nominal activities are also available The radiological hazard posed by the encapsulated Ba-133 (1.0 PCi) source is minimal. The dose rate at one foot from this source is at background levels. The only potential hazard is from direct handling of the source, with dose rates to the finger tips of about 2 mrem/hr for the Ba-133 source.
