A Tokyo Electric Power Co. employee refused in a recent interview to reveal how much radiation he has been exposed to during nearly a month working inside the Fukushima No. 1 nuclear plant.
"I can't tell you. It's personal information," said Yasuki Murata, a 44-year-old worker from the plant's planning and public relations section, batting away repeated questions about his radiation exposure in an interview Wednesday.
Since the March 11 earthquake and tsunami crippled the plant, causing it to spew radioactive materials into the environment, Murata has been staying on the plant's premises in a two-story quake-proof building whose few windows are covered with lead plates to keep out radiation.
