Regarding the June 16 Kyodo article "Tokyo ups radiation checks to 100 sites": I would like to inform you that the measured values reported in this article are meaningless unless you give a time that the values relate to, such as 0.06 microsievert per hour (which I assume you mean in this case). Otherwise, it's not known whether the values are significant, normal or even low. Could you also state normal average levels for comparison?
