The atoll is home to the Runit concrete dome, constructed in 1979 to temporarily store radioactive waste produced from nuclear testing by the United States military during the Cold War.
The typhoon caused significant damage to homes and infrastructure on the atoll when it hit on July the 5th.
Residents have expressed concerns about cracks which are slowly developing in the dome's concrete surface.
Our correspondent Giff Johnson says the storm would have churned up lagoon sediment which is laced with radioactive waste.
