Rod Sources

Designed to withstand the rigors of constant use.


Capintec offers a wide variety of Rod Sources for well counters to satisfy the needs of your department. These sources are used for calibrating well type NaI detectors. They are constructed of high-strength plastic to withstand the rigors of constant use in a busy department. They have a flat base which allows easy positioning in the vertical position required for consistent accuracy in the counting of many tests.

Capintec Rod Sources are calibrated as NIST traceable with an accuracy of ± 5% at the 99% confidence level. Each source consists of a lucite rod measuring 12.7 mm (0.5″) x 75 mm (2.95″) as a standard size. The active diameter of the rod source is 0.187″ (4.75 mm).
