各地の最大放射線量は昨年３月１４日以降の最大値を記録
各地で６日午前９時から７日午前９時までに観測された最大放射線量は、３～６日と比べ、関東や関西を中心に多くの地域で上昇した。
According to MEXT, radiation levels rose from the period of 9am on the 6th to 9am on the 7th across the Kanto and Kansai regions when compared with the previous 3 days.
文部科学省の集計によると、福島で０・９００マイクロシーベルト、茨城で毎時０・０８７マイクロシーベルトにそれぞれ上昇、愛知は０・０６２マイクロシーベルトと昨年３月１４日以降の最大値を更新した。北海道は０・０２７マイクロシーベルトに減少した。
Fukushima registered at 0.9 μSv/hr and Ibaraki at 0.087μSv/hr. Aichi prefecture measured in at 0.062μSv/hr which was the highest recording since 3/14/2011. On the other hand, Hokkaido decreased to 0.027μSv/hr.

Note that most government measuring devices are located well above ground level, in some cases on top of buildings. Typically, radioactivity levels increases the closer one gets to the ground. Though the actual measurements are not the focus here -- rather the issue is: What's causing the noticeable radiation spikes that are higher than these locations have seen in months?
