I recently wrote an article dealing with the risks of radioactive contamination associated with the consumption of food in Japan. This article was prompted by the publication of the first set of data estimating the distribution of the cesium throughout Japan's cultivable land^[1]. Earlier this month, the results of another significant effort led by researchers at the University of Tokyo was published^[2], this time, dealing with the doses of radioactive iodine to which the populations of the Tokyo area were exposed in the aftermath of the nuclear crisis triggered by the 11 March 2011 earthquake and tsunami and the crippling of the Fukushima Daiichi power plant. In very much the same way as last time, I propose to analyses this paper and try to extract the most significant information for the Tokyo residents or those wishing to visit Japan soon.
