Authorities in Russia's Pacific regions bordering Japan say they are trying to quell fears about wind-blown radiation from Japan.
Russian media say Pacific residents have rushed to buy iodine, wine and vodka that they believe can help avoid effects of radiation.
Olga Shekhovtseva, an emergency spokeswoman in the Primorsky region, said on Wednesday that companies dealing in iodine, face masks and radiation meters are stirring fears to boost sales.
Alexander Ivelsky, an emergency spokesman on the Sakhalin Island, says that constant monitoring of air and water proves that "no danger of radiation is expected."
Russia's State Meteorological Service says polluted air from Japan's tsunami-damaged Fukushima nuclear plant will bypass Russia. The plant is 1,500 kilometers (930 miles) from Fukushima.
