Re: Fukushima Daiichi site plan and daily on-site radiation readings

Readings up to 08:30, March 23 (in English). http://www.nisa.meti.go.jp/english/files/en20110323-2-3.pdf

An increase of around 30% is being observed at all measuring points at 08:30 (Page 5).

Readings up to 18:00 March 23. http://www.meti.go.jp/press/20110323012/20110323012-3.pdf

A number of measuring stations show increases at around 12:40 (see page 5)

Page 1 shows a significant increase between 14:10 and 16:10.

ground and water contamination readings up to March 22 are included. (P11-15)

The bump between 14:20 and 14:30 is due to a reading switch between point 4 (0.9 km from Unit 2) and point 5 (0.5 km away).

Readings to 08:30, March 25th; http://www.meti.go.jp/press/20110325005/20110325005-2.pdf

and to 12:00, March 25th. http://www.meti.go.jp/press/20110325006/20110325006-2.pdf

Significant increase (more than doubles) from 10:20 - 10:30, remains higher than before after this time.

Nuclide analysis updated to March 24.

Readings to 19:00 March 25. http://www.meti.go.jp/press/20110325012/20110325012-2.pdf

Pages 21 and 28 gives nuclide analyses from 3/24.

I-131 is 23 - 28 times permissable level. Cs-134 and Cs-137 also high.

P32 has sample analysis from what seems like 16 km from the plant with I-131 12.6 times higher than permitted amount.

Readings to 06:00 April 1: http://www.nisa.meti.go.jp/earthquake/monitor.pdf

Readings continue to trend downwards, but the position 3 is 1.1 km from Unit 2. I would like to see a return to data from Position 1 as we had before March 21 (see above) for a truer reading of on site radiation.
