S.E. International, Inc. S.E. International, Inc. designs, manufactures, and distributes radiation detectors under the Radiation Alert® brand. We engineer our instruments to be reliable, affordable, and intuitive. S.E.I. provides a diverse line of Geiger survey meters, radiation area monitors, radiation spectrum analyzers, software, and apps. Since 1979, we’ve helped protect the safety of people, facilities, and the environment with our line of nuclear radiation detectors. Compact handhelds offer high sensitivity to multiple types of ionizing radiation detection including alpha, beta, gamma, and X-ray radiation. At SEI, quality is a top priority and we ensure that our customers get the service and support they need. Our staff is committed to innovation, our customers, and excellence in radiation detection. We are dedicated to helping you find the appropriate instrument for your radiation detection needs. Thank you for your interest in our Radiation Alert® instrumentation. We look forward to serving you! Calibration & Service The Radiation Alert® Radiation Survey Meters come with a certificate of conformance from the factory (Typically ±15%) and hold a steady calibration. It’s generally recommend your instrument be calibrated annually from the date it was placed in service, but certain industries or applications may require them more or less frequently. If you want to include a NIST Source Calibration (±10%), please be sure to request one when purchasing a new unit. To have your radiation detector calibrated, please visit our Calibration and Service page for instructions and contact information. Our Calibration Service includes: Unit Operational Analysis, Certificate of Calibration with all applicable data NIST traceable Calibration (Calibrated using a Cs137 (662keV) beam calibrator Conforms to ANSI/NSC SLZ540.1.1994 and ANSI N323-1978.
