Harvard Affiliate Brigham and Women's and University Medical Center of Princeton Are Now Treating Patients Using Cesium-131 and Join Many Other Leading Medical Centers Throughout The Country

RICHLAND, WA--(Marketwired - Aug 13, 2013) -  IsoRay Inc. (NYSE MKT: ISR) (NYSE Amex: ISR) (, a medical technology company and innovator in seed brachytherapy and medical radioisotope applications, today announced it will host a booth at the 55th Annual Meeting of the American Society for Radiation Oncology (ASTRO). The annual meeting will take place September 22-24, 2013 in Atlanta, Georgia at the Georgia World Congress Center, and a number of papers are scheduled to be presented at the annual meeting on results achieved using IsoRay's products.

According to IsoRay CEO Dwight Babcock, "IsoRay now has more sales representatives speaking to the benefits of brachytherapy and presenting our products at new venues. We are seeing increased inquiries from the medical community about IsoRay's Cesium-131 (Cs-131) seeds, seed sutured mesh and GliaSite® for the treatment of a wide array of cancers throughout the body including brain, lung, ocular, gynecologic and prostate cancers. Our products offer an important advance over previous brain, head and neck, lung, prostate, abdominal wall and gynecological cancer treatments. With a number of papers being presented at ASTRO, we are encouraged as all of them showed very positive results realized in treating metastasized brain cancers, lung cancer and prostate cancer using Cs-131 or GliaSite®. Medical thought leaders recognize the need for a new powerful weapon in the battle against cancer and we believe Cesium-131 is that solution."

IsoRay has participated over the last quarter in the following industry shows, expanding its product awareness to differing specialists while sharing the benefits of Cesium-131 in their efforts to fight cancer:

1. American Brachytherapy Society (ABS) in New Orleans
2. American Association for Thoracic Surgery (AATS) in Minneapolis, Minnesota
3. American Association of Physicists in Medicine (AAPM) in Indianapolis, Indiana

IsoRay is also pleased to announce that Brigham and Women's (an affiliate of Harvard) and University Medical Center of Princeton have both recently begun treating patients using IsoRay products. Brigham and Women's has treated brain cancer and University Medical Center of Princeton has begun treating prostate cancer.

IsoRay's Cesium-131 sutured seeds, stranded mesh and the GliaSite® radiation therapy system each give physicians the ability to directly place a specified dosage of radiation in areas where cancer is most likely to remain after completion of brain tumor removal. The ability to precisely place a specified dose of radiation means there is less likelihood for damage to occur to healthy brain and lung tissue as well as critical structures compared to other alternative treatments. IsoRay's cancer fighting products reduce the ability of the tumor to recur, which means important benefits for patients in longevity as well as quality of life.

IsoRay is the exclusive manufacturer of Cesium-131. Cesium-131 is the first new isotope to be available in seed form for brachytherapy in approximately 20 years. Cesium-131 allows for the precise treatment of many different cancers because of its unrivaled blend of high energy and its 9.7 day half-life (its unequaled speed in giving off therapeutic radiation).

In addition to its CMS codes, Cesium-131 is FDA-cleared and holds a CE mark for international sales in seed form for the treatment of brain cancer, prostate cancer, lung cancer, ocular melanoma cancer, colorectal cancer, gynecologic cancer, head and neck cancer and other cancers throughout the body. The treatment can be deployed using several delivery methods including single seed applicators, implantable strands and seed sutured mesh, and several new implantable devices. IsoRay also distributes the GliaSite® radiation therapy system, used to treat brain cancers.
