Radioactive particles spewing from Fukushima Daiichi will affect the food chain.  Particles will collect on crops, and will end up in the ocean affecting sea life.

Taiwan has already started testing their own crops for signs of radiation contamination.  Russia has increased radiation monitoring from weekly, to daily.

Cows will graze on grass that is contaminated with radiation, and it will show up in the milk.

Thailand, South Korea and Singapore are testing food products from Japan.

Chinese officials have expressed concern about radiation levels in the ocean.

NHK reporting that reactors 5 & 6 overheating.  Coolant levels dropped. Fukushima Daiichi workers trying to cool them down with sea water.

Reactors 5 & 6 were supposed to be shut down before the 9.0 quake hit.

Here is another perspective on radiation levels: 1,000 millisieverts will cause radiation sickness, a single dose of 10,000 millisieverts is likely fatal.

Winds are currently blowing southeastward from Japan.

Emergency shelters are reaching their limits, due to people trying to flee possible radiation exposure.

Three concepts to think about when protecting yourself from radiation:  Time, distance and shielding.

The less time you spend in a radioactive environment the better.  The further away you are from a radioactive event the better.  If you can’t do those things then you need to be shielded, and the type of shielding depends on the type of radiation.

Alpha particles can be stopped by a sheet of paper.

Beta particles can be stopped by thick aluminum, and in the case of more potent Beta particles thick plastic, wood, Plexiglas or water.

X-ray and gamma radiation can be blocked with lead, depleted uranium or barium sulfate.

Neutrons can not be blocked, this type of radiation was detected at the Fukushima nuclear plant.  This is why the Neutron bomb is so bad.

It is not practical for most people to pack lead lined clothing, or line their house with lead, or to dig a deep underground shelter, etc.  Also, some forms of radiation contamination will remain for decades.  Practically speaking, for most people it is impossible to protect yourself from radiation contamination.

Officials at latest press conference have made statements that make it clear that there is confusion as to what is going on at the Fukushima Daiichi plant.

Statements made include the fact that there is confusion over types of units of radiation measurement.  Also, confusion over what is causing smoke coming from reactor 3, and confusion over what is causing some radiation readings to go up.

Now saying that reactor 4 actually exploded yesterday (not just fire).  Photos presented as proof, and to explain how spent fuel rods were exposed.

Fukushima officials say they are asking for help from the Japanese Self Defense Forces.  Situation rapidly changing at Fukushima plant 1 (Daiichi).

Smoke from reactor 3.  Radiation levels increasing.  Officials admit they are having trouble making clear which unit of measurement they are using for radiation levels.  Containment vessel in reactor 3 might be damaged.  Cause unknown at this point.  Confirming damage to reactor 2 suppression chamber.

Reuters, and NHK, reporting that the white smoke from Fukushima Daiichi, is coming from reactor 3.  It is suspected to be coming from the Spent Fuel Rod Pool of reactor 3.

NHK reporting another fire at the plant.  No details on the new fire.
