(AlJazeera) Scientists and doctors are calling for a new national policy in Japan that mandates the testing of food, soil, water, and the air for radioactivity still being emitted from Fukushima's heavily damaged Daiichi nuclear power plant.

"How much radioactive materials have been released from the plant?" asked Dr Tatsuhiko Kodama, a professor at the Research Centre for Advanced Science and Technology and Director of the University of Tokyo's Radioisotope Centre, in a July 27 speech to the Committee of Health, Labour and Welfare at Japan's House of Representatives.

"The government and TEPCO have not reported the total amount of the released radioactivity yet," said Kodama, who believes things are far worse than even the recent detection of extremely high radiation levels at the plant.

There is widespread concern in Japan about a general lack of government monitoring for radiation, which has caused people to begin their own independent monitoring, which are also finding disturbingly high levels of radiation.
