Cesium Irradiator Replacement Project

Considerations for Cesium Irradiator Replacement

While radioactive sources play an important role in commercial, medical, and research facilities, the benefits of these sources must be balanced with sufficient security to prevent radiological materials from falling into the wrong hands.

Cesium-137 is used in medical equipment such as in last generation radiotherapy systems or irradiators. Used in most countries around the world, with hundreds in the United States alone, the concerns over the dangerous radioactive isotope being used in a terrorist attack, and its safe and responsible disposable have caused issues for a long time.

Significant advancements in technology in recent years have yielded safe and effective alternative non-radioactive x-ray devices that are approved by the U.S. Food and Drug Administration. Replacing cesium-137 irradiators with these x-ray devices has both security and fiscal benefits: It requires less security and doesn’t require expensive disposal at the end of the machine’s life cycle.

Replacing your cesium irradiator with a non-radioisotopic alternative may offer your institution an opportunity to meet cost and throughput needs while permanently reducing security risks.

“By implementing the X-ray irradiator, we have further enhanced the safety of our testing and increased the security of our facilities. At the same time, the X-ray irradiator has enabled us to increase our throughput and has exceeded our expectations for performance and reliability.

CIRP – Cesium Irradiator Replacement Project

The Department of Energy’s (DOE) National Nuclear Security Administration (NNSA) Office of Radiological Security (ORS) is working with domestic users of cesium-137 based irradiators who are interested in converting to viable non-radioisotopic alternatives.

The Cesium Irradiator Replacement Project (CIRP), offered by ORS, provides qualified sites who are interested in making the switch with a financial incentive towards the purchase price of a new non-radioisotopic device, as well as the removal and disposal of the cesium irradiator.

The Project was launched in 2014, and is supported by the United States’ commitment to facilitate the replacement of 34 cesium-137 irradiators with non-radioisotopic alternatives by 2020.

For more information about the CIRP program download the official flyer.

Approved Vendor by the DOE

Qualified participants will receive:

  • Removal and disposal of the cesium-137 irradiator, saving the site approximately $100–$200k per irradiator.
  • A limited financial payment towards the purchase of the new non-radioisotopic device, up to 50% of the purchase price.
  • Training, warranty/maintenance agreement costs, and spare part costs are the responsibility of the site.

Xstrahl is an authorized vendor by the DOE, and with over 20 years experience in X-ray technology, our team can help guide you through this process with multiple systems to suit your needs.
