Radiological Monitoring for area of Fukushima Dai-ichi Nuclear Power Plant in Ibaraki Prefecture is provided in regularly updated tables via:

• http://www.mext.go.jp/english/radioactivity_level/
• Charts in PDF form are available via "Reading of environmental radioactivity level by prefecture, Time series data (Graph)" and "Reading of environmental radioactivity level".
• Readings from individual monitoring posts on land and off-shore in the area are also available via "Readings at Monitoring Post out of 20 Km Zone of Fukushima Dai-ichi NPP" and "Readings of Sea Area Monitoring at Post Out of Fukushima Dai-ichi NPP".

Interpretation Notes

1. Row 8 indicates Ibaraki Prefecture where Fuchushima Plant is based.
2. Charts are one page per day with one hour time slices per column.
3. Radiation dose is provided in microsieverts (μSv) per hour (μSv)
4. Page 3 provides a simple guide diagram for typical radiation dose rates per year.
5. Compare per hour and year doses by *24*365 (e.g. approx. 1.14 μSv per hour = 10,000 μSv per year).
