RadQual's calibrated rod sources typically have a calibration accuracy of ± 3% – 5% at a 99% confidence level. Physical dimesions are 2.96 inches (75 mm) total length by 0.47 inches (11.9 mm) diameter.
RadQual's calibrated rod sources are manufactured by gravimetric transference of NIST traceable solutions.
RadQual's rod sources are designed to mimic a tube source so there is no need to buy duplicate products.
