Radioactive soil in pockets of areas near Japan’s crippled nuclear plant have reached the same level as Chernobyl, where a “dead zone” remains 25 years after the reactor in the former Soviet Union exploded.

Soil samples in areas outside the 20-kilometer (12 miles) exclusion zone around the Fukushima plant measured more than 1.48 million becquerels a square meter, the standard used for evacuating residents after the Chernobyl accident, Tomio Kawata, a fellow at the Nuclear Waste Management Organization of Japan, said in a research report published May 24 and given to the government.

Radiation from the plant has spread over 600 square kilometers (230 square miles), according to the report. The extent of contamination shows the government must move fast to avoid the same future for the area around Tokyo Electric Power Co.’s Fukushima Dai-Ichi plant as Chernobyl, scientists said. Technology has improved since the 1980s, meaning soil can be decontaminated with chemicals or by planting crops to absorb radioactive materials, allowing residents to return.

“We need to finish this treatment as quickly as possible, within three years at most,” Tetsuo Iguchi, a specialist in isotope analysis and radiation detection at Nagoya University in central Japan, said in a telephone interview. “If we take longer, people will give up on returning to their homes.”
