Isoray is committed to pioneering innovative solutions that empower communities in the fight against cancer. Starting today, we’re rebranding our core products under the Cesium Blu brand as we build a modern brachytherapy toolset for clinicians. 

Higher Energy

At its core, Cesium Blu is powered by Isoray’s innovative and proprietary isotope Cesium-131. With higher energy and a shorter half-life than competitors, Cesium Blu is proven to be a highly customized and effective treatment for patients in the fight against cancer.
Now with Blu Build

A Complete Tool Set for Clinicians

With the introduction of Blu Build, in the fall of 2018, Isoray now has a complete tool set for our community of clinicians to administer breakthroughs in brachytherapy throughout the body.
Patient Focused

A Community of 13,000+ Patients

Cesium Blu puts patients first because it is highly effective in the treatment of cancer and its rapid resolution of side effects.  

Future Forward

Together, we’ll redefine brachytherapy.

Brachytherapy has always been one-of-many options in the fight against cancers – with the power of Cesium Blu we have the opportunity to cement it as the patient’s treatment option.

A Bold New Direction

We’re making Blu a part of everything we do.

With the introduction of Cesium Blu, we no longer have to battle with other isotopes. We’ll be leading the conversation and telling the stories of how our Cesium Blu branded products and services empower our customers and patients to fight cancer.

Together our ideas and energy will make it happen.
