The Associated Press reports that customs officials in Chile have detected radiation in cars that arrived from Japan onboard the Hyundai 106 cargo ship.
Twenty-one of the 2,500 cars that arrived in Iquique, Chile from the Japanese port of Yokohama have been found to have low levels of radiation.
Nearly one hundred port workers have protested the arrival of the shipment and subsequent exposure, claiming their health was at risk.
Chile’s nuclear commission confirmed that the levels of radiation found on the cars were too low to cause damage to humans. Officials say the cars will be washed while they're on the ship to keep any radiation onboard.
