OK this is a VERY preliminary look at the overhead but here is what I see (photo is enlarged and uncropped- lot of things going on in this one):
Red arrows = application of force.
Circles = area of interest
OK let's start with the green circle. Within this area you can see an upwards and outwards application of force. Something went up & out in a hurry- whether it was explosive venting, hydrogen explosion or something else... it left FAST.
The blue circle shows a lot of what appears to be charred material, most likely concrete and roofing materials. Whatever was under there was VERY hot.
Just to the "south" of that is a large scorch mark which is consistent with an explosion "next door". Pay attention to the red arrow showing a large AC unit being shoved to the left. This is consistent with a blast coming from out of frame to the "south".
The red arrow on the far left shows a large diameter pipe or duct bent back onto itself, again showing a high order explosion somewhere "south" and out of frame. The same applies to the toppled stack at top right and general movement of the roof structure and wall damage near scorch mark.
The building at the bottom of the photo has holes in it as well but this is from airborne objects punching DOWN through the roof. You can see the curve of what appears to be rebar at the edges.
To-date, levels recorded at this monitor have been thousands of times below any conservative level of concern.
How does plutonium change in the environment?
All isotopes of plutonium undergo radioactive decay. As plutonium decays, it releases radiation and forms other radioactive isotopes. For example, Pu-238 emits an alpha particle and becomes uranium-234; Pu-239 emits an alpha particle and becomes uranium-235.
This process happens slowly since the half-lives of plutonium isotopes tend to be relatively long: Pu-238 has a half-life of 87.7 years; Pu-239 has a half-life is 24,100 years, and Pu-240 has a half-life of 6,560 years. The decay process continues until a stable, non-radioactive element is formed.
Top of page How do people come in contact with plutonium? Residual plutonium from atmospheric nuclear weapons testing is dispersed widely in the environment. As a result, virtually everyone comes into contact with extremely small amounts of plutonium.
People who live near nuclear weapons production or testing sites may have increased exposure to plutonium, primarily through particles in the air, but possibly from water as well. Plants growing in contaminated soil can absorb small amounts of plutonium.
What can I do to protect myself and my family from plutonium? Since plutonium levels in the environment are very low, they pose little risk to most people. However, people who live near government weapons production or testing sites may have higher exposure. Plutonium particles in dust are the greatest concern, because they pose the greatest health risk. People living near government weapons facilities can track radiation monitoring data made available by site personnel. If radiation levels rise, they should follow the radiation protection instructions given by site personnel.
How do I know if I'm near plutonium? You must have special equipment to detect the presence of plutonium.

For figuring out exact blast forces I'd need a lot of info on hand as far as structural materials used, exact dimensions, concrete mix (approximation) as well as a lot of other things.
Based on a SWAG (after a few beers) IMO you're looking at no less than 15 psi in overpressure.
10 psi kills in an enclosed structure and will blow walls out of normal concrete buildings. 4 psi will blow a typical wood frame house.
This was min 15 psi UNENCLOSED. That is huge. Like really, really big. MOAB big.

I honestly can't understand why they are even taking the boat out... is there no information reaching Japan?

I am not sure what the U.S is doing with inbound ships..
As the concerns mount over radiation leaking from the crippled Fukushima Daiichi nuclear power plant in Japan, governments around the globe have announced various steps to monitor or screen ships and aircraft arriving from the quake-stricken country. So far, few ships or planes appear to have registered unusual radiation levels or suffered holdups because of contamination fears.
One of China’s largest ports, Yantian port in Shenzhen, next to Hong Kong, announced Friday that it had begun screening all arriving vessels and containers for radiation if they had been to Japan in the preceding 28 days and if Yantian was their first port of call in China. These vessels will not be allowed to unload until after all screening has taken place.

How is iodine getting everywhere in the US, is the half life not only 8 days? If it is getting that far does that mean it's in the jet stream or are we just getting the second "half", as in half has already decayed? Also is the half life the same when it is in stuff like milk? As in if it is older than 8 days it is half as radioactive?
Sorry for the bombardment of questions buddy, I blame you though because you know too much.
