Decontamination workers wearing protective suits and masks remove radiated soil and leaves from a forest in Tomioka town, Fukushima prefecture, near Tokyo Electric Power Company's (TEPCO) tsunami-crippled Fukushima Daiichi nuclear power plant on February 24, 2015. Many residents of Okuma, a village near the stricken Fukushima Daiichi plant, are angry about government plans to dump some 30 million tons of radioactive debris raked up after the March 2011 nuclear disaster in a sprawling waste complex on their doorstep. Few believe Tokyo's assurances that the site will be cleaned up and shut down after 30 years. In the four years since the disaster, Japan has allocated more than $15 billion to lower radiation levels around the plant. Every day, teams of workers blast roads with water, scrub down houses, cut branches, and scrape contaminated soil off farmland. That radiated trash now sits in plastic sacks across the region, piling up in abandoned rice paddies, parking lots and even residents' backyards. #
