Residents in the central province of Quang Ngai are worried about a radiation leak since a sensitive radioactive instrument disappeared from a dam construction site on Sunday.
The machine was used to measure the technical vibration and the concrete pressure at the plant, which is expected to generate 520.8 million kWh every year once it is put in operation.
People are afraid that the thief will break the machine into pieces to sell for scrap metal, local news website VietNamNet said Wednesday.
Thousands of workers and residents live around the construction site at the Dakrinh hydropower plant.The plant will mainly provide power to develop Dung Quat Economic Zone in Quang Ngai.
Local police say their investigation is under way.
