Furthermore citizens of Greece residing on islands and non-metropolitan areas will have more access to localized care, while providing patients with a better quality of life than many competing treatments.

IsoRay Chairman and CEO Dwight Babcock commented, "We are very optimistic about the unique opportunities for growth in Greece for our expanding product line and look to the international market to contribute in the future of IsoRay's profitability. IsoRay's products currently carry FDA clearance and the CE Mark, making them eligible to be sold in 31 European nations. Physicians and institutions throughout the US are continuing to report outstanding results in the use of our Cs-131 seeds for brain cancer, head and neck cancer, prostate cancer and lung cancers. As peer reviewed papers are released we anticipate a growing acceptance and interest in our products.
