Since TEPCO has (as of 2010 according to Wikipedia) 38,671 workers, I wonder how they decided which 6,671 didn't get to go to the plant in the first few days after the accident to get a dose?
I had similar issues with my progressive lenses, so at my last appointment, I asked to get two pairs of glasses - one with normal far vision and another pair of reading glasses for up close. (I also had the need to use up $1000 in a flexible spending account that could only be used for vision and dental - my son didn't get braces this year, like I thought he would!). I thought this would be a lot better. I could see all my monitors in focus with my normal glasses, and only when I want to read a book would I switch to my reading glasses. My optomitrist recommened against my choice, but I did it, anyway.
While I am happy with my new normal pair of glasses when working on the computer, I am frustrated when using my phone (the iPhone 6 Plus, so it's not a tiny screen). I find myself moving my phone farther away to be able to read it. This happens to me all the time, so it gets very annoying. I think a better choice would have been a pair of progressive lenses for every day use and a separate pair for just the distance to the computer screens, and I'd leave those at work. If I only had the budget for a single pair, I'd go back to the progressive lenses.
Is there any plan to introduce new professions or open up new branches to existing professions?
I have a level 60 hunter that is a leatherworker. I still haven't chosen a specialty in leatherworking, because I don't like any of the gear for my character. The Dragonscale armor doesn't add agility. The Elemental armor does, but it's not mail. Is there any plan to add either mail elemental pieces or agility-adding Dragonscale armor?
Or do you have plans for new professions? How about wood-working? The gathering skill would be to farm wood from certain trees in the world. The player could make bows and arrows. Maybe they could make boxes, crates, chests, etc. that are containers larger than the comperable tailored bags, but could only be used in bank slots, and not carried with items in them.
You need to follow the regulations in 14 C.F.R. Part 420. You can find the link here: http://ast.faa.gov/lrra/regulations/fr19oc00.htm
You have to be able to show that an actual vehicle (not theoretical) can fly from your launch site and meet the expectation of casualty requirement (any launch has less than 30 in a million chance of causing a casualty to the uninvolved public).
You also need to complete an environmental assessment, which will take several years and lots of money.
Actually, it's the first license for a reusable launch vehicle. (It just happens to be suborbital) The FAA has had regulations on the books for RLVs since about 1999, but no one had applied for a license until the past year. They still have 2 more applications in the works.
The X Prize requires teams to obey all applicable laws. An FAA launch license is required by American citizens/companies (where every they launch from) or foreign citizens/companies launching from the U.S. The Canadian, Russian, Romanian, etc. teams will not need an FAA license, although they will need whatever approval their country comes up with. Many of those companies look to the FAA to see how we do it, since the FAA is the only one to have any published rules for launching RLVs.
There are many requirements, but it boils down to a few big parts:
You must be able to complete the launch through landing with a risk to the uninvolved public (you can kill yourself) of less than or equal to 30 in a million.
You must have financial responsibility (e.g. insurance) in an amount set by the FAA (AST - Commercial Space Transportation) based on the worst accident with a 1 in 10 million chance of occurring (capped at $500M)
You must undergo an environmental review since the license is a "Major Federal Action" and therefore subject to NEPA. This takes a long time and costs a lot of money.
For an RLV (Reusable Launch Vehicle), you must use a "System Safety Process" to ensure safety. And you have to convince AST that it is sufficient. Expendable Launch Vehicle (ELVs) typically have to be able to blow up the vehicle if it goes off course, but vehilces with pilots don't really want to do that for some reason...
The insurance requirement is set by determining the Maximum Probable Loss (MPL). AST (the office of the FAA that licenses the launch) determines what the worst accident that has a 1 in 10,000,000 probability is, and sets the insurance requirement based on that accident. It is capped by Congress at $500M. Most are in the $100M - $250M range. The less likely you are to kill anyone (not associated with the launch - it doesn't include your own people), the less iunsurance you need.
The FAA office that licenses launches, AST (much shorter than Associate Administrator for Commercial Space Transportation)only licenses launches and reentries. Once you are up there, you are not under their jurisdiction.
Also there is another option to the choices of issuing a license and telling Congress they didn't meet the deadline. They can also issue a denial of a license. They have 180 days to make a license determination. That does not mean it has to be favorable to the applicant.
LOX isn't compressed oxygen, it's liquid. It's also VERY cold. Almost -300 degrees F. If the tank ruptures in the cockpit, the pilot may have to worry about being frozen (a' la Terminator 2) as well as any fire hazard or shrapnel.
Hydrogen Peroxide or any other monopropellant decomposes (energetically) as opposed to "burning".
A propellant leak can be VERY dangerous, or it can be benign, depending on the location and severity of the leak. If a valve has a slight leak, it may not be much of a problem. If you have a ruptured propellant tank... well, you are having a very bad day.
I was a Navy nuke, so I know a thing or two about radiation. What people think of as "radiation suits" are not designed to shield radiation. They are used to prevent contamination. The suit prevents radioactive material from getting on your skin and clothes, so that you don't take it home with you.
There are several kinds of radiation.
Alpha particles are helium nuclei (He4). These particles are not dangerous unless you ingest or breathe them into your lungs. The dead layer of skin on your hand is enough to stop them. If they get into your body, they cause serious harm, as there is no "dead layer" of anything to stop them.
Beta particles are electrons. They are light and fast, so they penetrate more. They will give you a dose to your skin, but not much deeper than that. A contamination suit can probably stop Betas. Even the old ones.
Gammas are photons/electromagnetic radiation. Whatever you want to call them. X-Rays, microwaves, and radio waves all fall into this general category. The real biological hazard comes from the high energy particles/waves. These will pass right through your skin and can affect your internal organs. A contamination suit is not expected to reduce the dose from gammas.
neutrons are produced in fission and some rare decay events, mostly shortly after a fission event. Neutrons are the only thing that can make something ELSE radioactive. Neutrons have no charge, so shielding them is difficult. It takes LOTS of lead or iron or water, etc. I don't care what their material is made of, if it's light enough to wear, it will not shield neutrons well.
The web site said that it shileds low energy gammas, alphas, and betas. Low energy gammas don't cause much harm. Unless you work with a low energy gamma source on a routine basis, this material is not going to change your life. Or your life expectancy.
This is my first post. Is it WAY too long? Sorry.

NASA does not need FAA approval to do anything, except getting airspace clearance. NASA and the military operate under their own rules.

By the way, XCOR is not an X-Prize contender.
