Relief from cancer and other serious diseases can be provided by radiation treatments. But those treatments pose risks because too much exposure to radiation can trigger other medical problems. Kaushal Rege, a Fulton Schools professor of chemical engineering (second from left in photo) is part of a research team testing a new device that could prevent such complications by providing more exact measurements of radiation dosages. Rege is partnering with the Banner MD Anderson Cancer Center in Gilbert, Arizona, to develop a device that uses a gold nanogel to reveal dosage amounts to enable medical practitioners to keep radiation exposure at healthy and effective levels.
