TOKYO - Radiation injuries to three workers complicated the battle to control Japan's crippled nuclear plant on Friday and heightened global anxiety over the worst atomic crisis in 25 years.
Hailed by Japanese as anonymous heroes braving unknown dangers, about 300 engineers have been working around the clock to stabilize the six-reactor Fukushima complex since an earthquake and tsunami struck two weeks ago.
But they had to pull out of some parts of the complex, 240 km (150 miles) north of Tokyo, when three workers replacing a cable near reactor No. 3 were exposed to high contamination by standing in radioactive water on Thursday, officials said.
Two were taken to hospital with possible radiation burns after the water seeped over their boots.
