SHINE Medical Technologies, a former Monona company that plans to manufacture a safer, more affordable version of a key element in diagnostic medical procedures, broke ground this week on the first building on its new campus in the Janesville area.

Building One will house SHINE’s first fully integrated production system for molybdenum-99, a radioactive isotope that decays into technetium-99m, which is used in millions of medical imaging scans for cancer and heart problems each year.

Building One also will be a “technological genesis building,” said SHINE founder and CEO Greg Piefer. “It’s intended to be a laboratory in which we’re going to continue to develop new technologies to keep SHINE at the forefront of not just medical isotope production, but to go beyond that.”
