ERS rod sources are calibrated by direct
comparison of standardized solutions traceable
to the National Institute of Standards and
Technology (NIST), in an identical geometry, using
a pressurized ion chamber with ±%5 accuracy.
Source dimensions are 12.7 mm x 127 mm (0.5”x 5”) / 12.7 mm x 74.9mm (0.5”x 2.95”).
ERS rod sources can be supplied in set or
individually in accordance with customer request.
ERS offers a wide range of rod sources that
are used for calibrating well counters and
thyroid uptake systems. Rod sources are
constructed of acrylic material and have a
flat base which allows easy positioning in
the vertical position required for consistent
accuracy of the calibration process.
