One of the few workers to be tested for radioactivity after March's nuclear disaster in Japan is exhibiting over 10 times the accepted levels .

My measured value exceeded the standard value by a double-digit factor. That's never happened before, a plant worker told Japan's Yomuri.

The man, an employee of a company that works with TEPCO, installed power cables near a reactor building at the plant for a month beginning at the end of March.

While a normal internal radiation level would range from several hundred to 1,000 counts per minute , he was told his level was 30,000 cpm.

The report noted that there were high levels of radiation in the parts surrounding the mans work area.

And although the masks worn by workers are supposed to be changed every three hours, he was told by a management that he did not have to change it if there was no radioactive contamination. He therefore used a single mask for five to six hours.

As of May 8, 630 workers, or just 10 percent of all workers at the plant, had taken the test, the paper reported.

More than two months after a 9.0 magnitude earthquake and a deadly tsunami set off the worst nuclear disaster since Chernobyl.

More than 70,000 people have been forced to evacuate their homes because of health risk and last week the government workers began killing more than a 1,000 cattle which were within the Fukushima no-go zone.

The government has retaliated by declaring a plan to help the Tokyo Electric Power Company (TEPCO) to pay the victims of the crisis with the money they draw from other organizations and taxpayers. The plan has to be approved by parliament as opposition has already showed its dissatisfaction.
