Radiation background is steady at higher than normal levels. Fallout is increasing slightly. Cesium levels are increasing in water and fallout.
-
Cesium is going to be around for a long time (30 year half life). Best to keep wearing masks until the plant is sealed. Best to drink bottled water as long as cesium is detected.

Radiation in Chiba is leveling off at a higher than normal level. Still at about 13 chest xrays per year. About twice normal levels.
-
Drinking water radiation is still declining.
-
Chiba fallout is up again. Must be having trouble at the plant. I think that is why the radiation did not drop more.

-
Drinking water radiation is still declining. About 1 chest xray per year
-
Fallout is low. They are controlling releases from the plant. Keeping water on fuel rods.

March 29, 2011
-
Radioactivity: Because there is less getting out of the plant, levels in radioactivity levels in Chiba and Tokyo are decreasing according to the decay of iodine 131 with a half life of 8 days. Every day a small decrease. Levels are still above background, comparable to about 13 chest xrays per year.
-
Drinking Water: Levels in Chiba are lower than yesterday, showing fairly low levels. If you have access to bottled water, then use that instead of tap water. I will be happiest when the level is down to background levels.
-
Fallout (Dust on the ground): Levels are the same as yesterday. At least there was no increase. Levels are fairly low. Continue to be careful.
-
Winds: Winds at the plant seem to be continuing toward the east, so most (if any) of the fallout is going out to sea. Good news for Chiba and Tokyo.
