RadTran has received a Phase I STTR award from the UnitedStates Department of Energy to support commercialization of its Ra-228 production process as a means for supporting Ac-225 isotope needs. The project under the award entails three major steps including: Ra-228 product proof of concept demonstration, Ra-228 to Th-229 conversion demonstration, and process scalability. Experimental work is being conducted at the Pacific NorthwestNational Laboratory.
