Data from power plants:

Stack of each power plant has different name, and some plwer plant has more than one stack.
In this site, each name is displayed like“stack monitor 1”, or “stack monitor 2” in each graph or list, and detailed contents are shown in the list below.
When some power plants share the same discharge canal, they also share “discharge canal monitor”.
In this site, such discharge canal monitor is displayed in each graph or list of each power plant sharing the same discharge canal.

Characteristics of monitoring station using electronic dosimeter

Monitoring stations using electronic dosimeter tend to indicate high measured values and fluctuate in 10 minute graph with prefecture monitoring station. Because of differences in heights of indicator and detectable energy range.

heights of indicatordetectable energy range
Monitoring station using electronic dosimeter1m60kev-6Mev
Prefecture monitoring stations2.4m50kev-3Mev
