💨 Abstract

A concrete dome on Runit Island in the Marshall Islands, built to contain radioactive waste from Cold War-era nuclear tests, is deteriorating. The Runit Dome, constructed in the late 1970s, is showing cracks and allowing seawater to seep in, potentially spreading radioactive material into the ocean. The site, near the ocean's edge, is threatened by rising sea levels and shifting groundwater.
