Authorities in Thailand expanded their search Wednesday for a metal cylinder with radioactive contents that has gone missing from a power plant, warning the public that it poses a danger to health.
The 30-centimeter- (12-inch-) long cylinder containing the radioactive material Caesium-137 was discovered missing last Friday from a piece of machinery at a steam power plant in Prachinburi province, 100 kilometers (60 miles) east of Bangkok.
