Create a Chart or Table

Select Chart Type

Using data registered to the Environmental Radiation Database, you can create charts and tables of air radiation dose rates, annual changes, concentration ranges, and statistical summaries under the conditions you specify. You can easily create a chart or table by selecting the type you wish to generate and following the instructions displayed on your screen. Please note that some data for the atmosphere and ocean cannot be specified for certain prefectures, and you cannot create charts for such data.

• Ambient Dose Rate Map

  

  You can create a chart in which ambient dose rate data (maximum, average, minimum) are plotted.

• Create a Summary Table

  

  You can create a summary table by specifying conditions such as survey year and survey area.

• Aggregated Ambient Dose Rate

  

  You can create a statistical table of spatial dose rates based on the measurement results from monitoring posts established in all 47 prefectures through the Environmental Radiation Level Survey.
