The use of copper-67 radioisotope has been severely limited up to this point because it has traditionally been difficult to obtain, often contained impurities and was expensive. Iotron is working with partners to commercialize a new production method based on enriched zinc-68 targets and a compact electron beam accelerator.
A patented sublimation process separates the copper-67 from the target which also facilitates rapid and efficient enriched target material recycling. The resulting copper-67 has high specific activity and low chemical and radiochemical impurity levels. There are four granted US patents which are listed on our website: www.copper67.com.
