In an effort to limit community transmission of COVID-19, RSSI is reducing in-office staff time.  RSSI is still open for business, but as a result of the reduced staffing, turn-around times for responses, order fulfillment, lab analyses, and instrument calibrations may increase.


Alpha / Beta Counting Services

Many types of samples are suitable for analysis by low-cost alpha/beta internal proportional counting.  This method is preferred for source leak tests, air monitoring samples, and surface contamination wipes.  For samples where the radionuclide is known or where gross counts are sufficient, alpha/beta internal proportional analysis provides rapid results with the lowest analysis costs.  Samples are analyzed within 5 business days of being received in our lab and the results can be mailed, emailed, and/or faxed to you.  In emergency situations, samples can be analyzed immediately upon receipt and the results sent back to you by email or fax in just a few hours.

Typical MDAs:

Alpha:   3.2×10-2 Bq (8.8×10-7 µCi)
Cs-137: 1.6
×10-1 Bq (4.3×10-6 µCi)
H-3:      8.0
×10-1 Bq (2.2×10-5 µCi)
