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 12.7mm x 127mm (0.5”x 5”) / 12.7mm 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.
