| NARAHA, Japan — The decontamination crews at a deserted elementary school here are at the forefront of what Japan says is the most ambitious radiological cleanup the world has seen, one that promised to draw on cutting-edge technology from across the globe. | NARAHA, Japan — The decontamination crews at a deserted elementary school here are at the forefront of what Japan says is the most ambitious radiological cleanup the world has seen, one that promised to draw on cutting-edge technology from across the globe. |
| But much of the work at the Naraha-Minami Elementary School, about 12 miles away from the ravaged Fukushima Daiichi nuclear power plant, tells another story. For eight hours a day, construction workers blast buildings with water, cut grass and shovel dirt and foliage into big black plastic bags — which, with nowhere to go, dot Naraha’s landscape like funeral mounds. | But much of the work at the Naraha-Minami Elementary School, about 12 miles away from the ravaged Fukushima Daiichi nuclear power plant, tells another story.

| More than a year and a half since the nuclear crisis, much of Japan’s post-Fukushima cleanup remains primitive, slapdash and bereft of the cleanup methods lauded by government scientists as effective in removing harmful radioactive cesium from the environment. | More than a year and a half since the nuclear crisis, much of Japan’s post-Fukushima cleanup remains primitive, slapdash and bereft of the cleanup methods lauded by government scientists as effective in removing harmful radioactive cesium from the environment. |
| Local businesses that responded to a government call to research and develop decontamination methods have found themselves largely left out. American and other foreign companies with proven expertise in environmental remediation, invited to Japan in June to show off their technologies, have similarly found little scope to participate. | Local businesses that responded to a government call to research and develop decontamination methods have found themselves largely left out.

| Recent reports in the local media of cleanup crews dumping contaminated soil and leaves into rivers has focused attention on the sloppiness of the cleanup. | Recent reports in the local media of cleanup crews dumping contaminated soil and leaves into rivers has focused attention on the sloppiness of the cleanup. |
| “What’s happening on the ground is a disgrace,” said Masafumi Shiga, president of Shiga Toso, a refurbishing company based in Iwaki, Fukushima. The company developed a more effective and safer way to remove cesium from concrete without using water, which could repollute the environment. “We’ve been ready to help for ages, but they say they’ve got their own way of cleaning up,” he said. | “What’s happening on the ground is a disgrace,” said Masafumi Shiga, president of Shiga Toso, a refurbishing company based in Iwaki, Fukushima.

| Shiga Toso’s technology was tested and identified by government scientists as “fit to deploy immediately,” but it has been used only at two small locations, including a concrete drain at the Naraha-Minami school. | Shiga Toso’s technology was tested and identified by government scientists as “fit to deploy immediately,” but it has been used only at two small locations, including a concrete drain at the Naraha-Minami school. |
| Instead, both the central and local governments have handed over much of the 1 trillion yen decontamination effort to Japan’s largest construction companies. The politically connected companies have little radiological cleanup expertise and critics say they have cut corners to employ primitive — even potentially hazardous — techniques. | Instead, both the central and local governments have handed over much of the 1 trillion yen decontamination effort to Japan’s largest construction companies.

| The construction companies have the great advantage of available manpower. Here in Naraha, about 1,500 cleanup workers are deployed every day to power-spray buildings, scrape soil off fields, and remove fallen leaves and undergrowth from forests and mountains, according to an official at the Maeda Corporation, which is in charge of the cleanup. | The construction companies have the great advantage of available manpower.

| “In such a big undertaking, cost-effectiveness becomes very important,” said Takeshi Nishikawa, an executive based in Fukushima for the Kajima Corporation, Japan’s largest construction company. The company is in charge of the cleanup in the city of Tamura, a part of which lies within the 12-mile exclusion zone. “We bring skills and expertise to the project,” Mr. Nishikawa said. | |
| Kajima also built the reactor buildings for all six reactors at the Fukushima Daiichi plant, leading some critics to question why control of the cleanup effort has been left to companies with deep ties to the nuclear industry. | |
| Also worrying, industry experts say, are cleanup methods used by the construction companies that create loose contamination that can become airborne or enter the water. | Also worrying, industry experts say, are cleanup methods used by the construction companies that create loose contamination that can become airborne or enter the water. |
| At many sites, contaminated runoff from cleanup projects is not fully recovered and is being released into the environment, multiple people involved in the decontamination work said. | At many sites, contaminated runoff from cleanup projects is not fully recovered and is being released into the environment, multiple people involved in the decontamination work said. |
| In addition, there are no concrete plans about storing the vast amounts of contaminated soil and foliage the cleanup is generating, which the environment ministry estimates will amount to at least 29 million cubic meters, or more than a billion cubic feet. | In addition, there are no concrete plans about storing the vast amounts of contaminated soil and foliage the cleanup is generating, which the environment ministry estimates will amount to at least 29 million cubic meters, or more than a billion cubic feet. |
| The contaminated dirt lies in bags on roadsides, in abandoned fields and on the coastline, where experts say they are at risk from high waves or another tsunami. | The contaminated dirt lies in bags on roadsides, in abandoned fields and on the coastline, where experts say they are at risk from high waves or another tsunami. |
| “This isn’t decontamination — it’s sweeping up dirt and leaves and absolutely irresponsible,” said Tomoya Yamauchi, an expert in radiation measurement at Kobe University who has been helping Fukushima communities test the effectiveness of various decontamination methods. “Japan has started up its big public works machine, and the cleanup has become an end in itself. It’s a way for the government to appear to be doing something for Fukushima.” | “This isn’t decontamination — it’s sweeping up dirt and leaves and absolutely irresponsible,” said Tomoya Yamauchi, an expert in radiation measurement at Kobe University who has been helping Fukushima communities test the effectiveness of various decontamination methods. “Japan has started up its big public works machine, and the cleanup has become an end in itself.

| In some of the more heavily contaminated parts of Fukushima, which covers about 100 square miles, the central government aims to reduce radiation exposure levels to below 20 millisieverts a year by 2014, a level the government says is safe for the general public. But experts doubt whether this is achievable, especially with current cleanup methods. | In some of the more heavily contaminated parts of Fukushima, which covers about 100 square miles, the central government aims to reduce radiation exposure levels to below 20 millisieverts a year by 2014, a level the government says is safe for the general public.

| After some recent bad press, the central government has promised to step up checks of the decontamination work. “We will not betray the trust of the local communities,” Shinji Inoue, the environment vice minister, said Monday. | After some recent bad press, the central government has promised to step up checks of the decontamination work. “We will not betray the trust of the local communities,” Shinji Inoue, the environment vice minister, said Monday. |
| There had been high hopes about the government’s disaster reconstruction plan. It was announced four months after the March 2011 disaster, which declared Japan would draw on the most advanced decontamination know-how possible. | There had been high hopes about the government’s disaster reconstruction plan.

| But confusion over who would conduct and pay for the cleanup slowed the government response. It took nine months for the central government to decide that it would take charge of decontamination work in 11 of the heaviest-contaminated towns and cities in Fukushima, leaving the rest for local governments to handle. | But confusion over who would conduct and pay for the cleanup slowed the government response.

| The Japanese government also made an initial effort to contact foreign companies for decontamination support. It invited 32 companies from the United States that specialize in remediation technologies like strip-painting and waste minimization, to show off their expertise to Japanese government officials, experts and companies involved in the cleanup. | The Japanese government also made an initial effort to contact foreign companies for decontamination support.
