A mass of air from the north could bring radiation dust directly from quake-hit Japan today, but the health impact would be negligible, the Observatory said yesterday. After four days when there was no radioactive iodine-131 in the air, the city might have radionuclide - a radioactive chemical substance - by today under the influence of an air mass from the west coast of Japan and along the eastern coast of the mainland.
