Food not checked for radiation poses risk in Fukushima: study


Eating unchecked homegrown vegetables and wild game from radiation-tainted areas on a regular basis can lead to high levels of internal radiation exposure, according to the results of a study published Tuesday in the U.S. online science journal PLOS ONE.

However, levels of radioactive cesium detected in the bodies of the study’s participants declined once they stopped eating highly contaminated food, said the researchers, who called for renewed efforts to raise people’s awareness of risky foods at a time when public interest appears to be dwindling.

The study focused on Minamisoma, which stretches about 14 to 38 km north of the Fukushima No. 1 nuclear plant.

Researchers followed nine people, who were the only ones out of 30,622 examinees from the city to have internal cesium-137 levels greater than 50 becquerels per kilogram in screenings between March 11, 2012, and March 10, 2013.

That’s roughly equal to 0.1 to 0.2 millisieverts per year.


The study was led by Masaharu Tsubokura, a physician at the University of Tokyo’s Institute of Medical Science. He said even though most of the Minamisoma residents’ internal radiation exposure level are non-detectable, it’s time to think about ways to support those who have little knowledge about, or interest in food contamination, as prolonged internal exposure may increase their risk of developing cancer.
