A nuclear meltdown or explosion at Tokyo Electric Power Co.’s crippled plant is unlikely to pose a health risk beyond 50 kilometers (36 miles) of the site, doctors and scientists said.
Workers at the tsunami-damaged facility in northeastern Japan are battling to cool reactors and spent fuel to avert overheating and explosions that could spew radioactive material into the environment. Their chances of success may be improving, with the possible restoration today of electricity to two of the reactors that would aid cooling measures, the utility said.
