Is Radio-Active Iodine From Japan's Nuclear Plant Becoming Risk For the world?

Extremely low levels of radioactive iodine from the tsunami-hit Japanese nuclear plant have been detected in parts of the UK.
A statement from the Health Protection Agency said the "minutest traces of iodine" were being seen in the UK, with low levels detected at monitoring stations in Oxfordshire and Glasgow
The agency said there was no public health risk posed by the iodine, as the radiation dose received from inhaling air with the levels recorded in the past few days would be minuscule and much less than the annual background dose.
While levels may rise in the coming days and weeks, they will be "significantly below any level which could cause harm to public health", the HPA said.
The statement comes after the Scottish Environment Protection Agency (Sepa) said an air sampler in Glasgow had picked up iodine particles which they believe could be from the Fukushima nuclear plant in Japan.
The HPA said that trace levels of the radioactive chemical iodine-131 had been detected by measurements taken at a monitoring station in Oxfordshire on Monday. The measurements followed reports of iodine at monitoring stations in Glasgow and Oxfordshire.
Dr James Gemmill, Sepa's radioactive substances manager, said: "The concentration of iodine detected is extremely low and is not of concern for the public or the environment.
The fact that such a low concentration of this radionuclide was detected demonstrates how effective the surveillance program for radioactive substances is in the UK.
