The approach on SFO 28S is over water, so that isn't an issue. The problem was that they were descending still, and would have hit the water long before making the runway if the ATC hadn't yelled at them.
Here is what I posted in the "above" I referenced in my first reply to you: http://isis-online.org/risk/tab7 Effective annual radiation due to natural sources in Denver is 11.8 mSv/y
So, let's look at the summary of the article that we're posting on:
In 33 of the districts, or 77 percent of the total, radiation levels were still higher than the government-set standard of one millisievert per year. In areas near the Fukushima Daiichi nuclear plant, where decontamination has been carried out on an experimental basis, radiation levels remain 10 to 60 times higher than the official limit.
So, the self-imposed government standard Japan has used to decide whether the areas are safe to inhabit is 1 mSv/y, and 23% of the Fukishima Prefecture are below this, that is 10x lower than Denver. Of the experimentally decontaminated areas near to the plant, they are 10x - 60x higher than the government standard, so anywhere from equal to Denver to 6x what Denver has.
To put this into perspective, this "government standard" they have imposed is actually lower than the average background radiation in Japan (1.4 mSv/y), and less than 1/3 of the average background radiation in the USA (3.1 mSv/y). I don't think they are likely to get massive areas of their land lower than average, just by the laws of statistics, which makes me think the politicians are just fearmongering by setting such a low standard.
So, I've put my numbers and sources down. As I've said, I'm not a fanboy. There was contamination, sure, I'm not denying that. What I'm saying is that the amount, after some decontamination efforts, is small enough that in the big picture, given the amount of energy generated by the plant, it is negligible compared to emissions from coal or chemicals produced during solar panel production. I think nuclear is one of the safest power generation methods we have. We just need to move away from 70s technology and not do stupid things like build them where tsunamis and earthquakes can do a double-wammy, without sufficient safety mechanisms to handle that.
I'm not saying Denver is more dangerous than a spill of radioactive fuel - stop putting words in my mouth. I'm saying that the *decontaminated* area around Fukishima has an order or magnitude less radioactivity than Denver when you measure it using a metric which accounts for what causes harm to humans.
I don't see why using a measurement of what causes harm to human is stupid, or why it makes me a liar.
I understand where you're coming from. But do you see my point? Any non-anti-terrorist usage of the system is illegal and against the principles upon which it was founded, so if you want to know whether people think that the system is being abused, you ask them whether it is being used for 'other' uses.
Well forgive me (or don't), but that was all in response to your degrading "high school" and "stop being stupid" comments. However, you still haven't given an answer as to why you think Sieverts is a bad way of comparing radiation. You mumbled something about alpha/beta particles, but I explained how that was already taken into account. Do you have any other reasons for thinking Sieverts are a bad way of comparing radiation dosages?
This was 10 minutes from the capital city along the main highway that links to South Africa. It was really a show of force, but the point is that it was completely normal. You regularly see roadblocks with police who have AK-47s, I think they just realised that giving each policeman an assault rifle is cheaper than giving them a car, and just as effective at making sure people stop. But really, apart from the bureaucrats, the Mozambicans were some of the friendliest people I have come across.
They only pulled us over because we had a foreign licence plate. The other cars on the road were mostly in terrible condition, but one tiny licence plate slip (which we couldn't fix until we were over the border anyway) and it's a full assault team with the officer making threats they knew we wouldn't contemplate facing.
Speaking of DiceDot, I noticed that downloads from Sourceforge ending in.exe don't actually download the file, but instead download special "Sourceforge Installer" crapware instead. What really pissed me off was that it didn't work behind my university proxy. So not only do I not have access to the original.exe, but the installer that probably cost them hundreds of thousands to deploy doesn't give it to me either.
Well, the system was put into place to specifically deal with terrorist activities, so if it isn't being used for that, surely all those other uses should be lumped together into "other"?
Dunno about 'best armed' either. When I was in Mozambique, as we were driving out we got pulled over by a police truck because our front licence plate had been knocked off. In the back of the truck were 8 guys with AK-47s. And this wasn't some SWAT team or anything, just a truck patrolling the highway and enforcing traffic rules.
Anyway, we bribed them ~$100 and they let us go. It was either that or have our vehicle impounded for the weekend.
So, getting back to this. What is "silly" about the Sievert? You haven't really given me anything to go on, and everything I have seen says Sieverts are a great way to measure it.
And I find it really funny how you think it is Cut and Paste. Not the "can't even bring myself to laugh", funny, I'm genuinely chortling here. Clearly you don't believe that I'm capable of writing that, and your only way of maintaining your current world view is by attributing what I've written to an external source. "Search your feelings^H^H^H^H^H^H^H^Hpreconceptions, Luke^H^H^H^HdbIII."
Does your mom drive you everywhere? Because it seems to me you've never used the metro in a major city, ever.
Sorry, but that was uncalled for. Not everybody lives in a metropolis with great public transport. Where I used to live didn't have any subway/train system at all. Where I am now there is marginal train coverage, but if you don't take it in rush hour you'll probably reach your destination minus a few personal possessions. If you want to take a phone or laptop with you during off-peak hours driving is the only safe option.
I'm very aware different sources of radiation have different effects due to different wavelengths/particles (alpha/beta/gamma/neutron). However, by definition, the Sv takes these different effects into account. When I say Denver has 10 mSv/y due to Radon, this already accounts for the different methods of exposure, because Sv is defined as the ionising radiation dosage absorbed by human tissue. In terms of how much damage is done to a human body (which is what we should be interested in), 10 mSv/y due to Radon is the same as 10mSv/y due to caesium-137. By definition. Do you dispute the definition of the Sievert? What exactly about this makes you think your understanding is so much greater than mine? We're not talking about Grays or Curies here. We're talking about Sieverts.
Here's a clear, to the point article explaining the difference between the different units of measurement. If you read it, you'll find that unlike Grays, Sieverts already accounts for the difference in danger between alpha/beta/gamma/neutron, and even between the different parts of the body the radiation targets.
BTW, your extremely condescending attitude is a personal attack, particularly when accompanied by no enlightening knowledge which would at least support your position or (preferably) allow me to improve my own knowledge of the topic. Please don't pretend to be so stupid that you can't recognise this. There is a difference between blindly putting somebody down by telling them they are juvenile and wrong, and trying to teach them through relevant information that they are incorrect. The first is a personal attack, the latter is civilised discourse.

I think Git is your best bet, since Google Code doesn't allow downloads any more.

Just ask if you can pay a spot fine. Their response should be fairly informative.
But then they'd have to pay tax on it. And you know what beancounters would think of that.
