What equipment does it take to take these kinds of detailed readings (iodine 131)? I've considered running a simple DIY geiger counter RadMon monitoring kit ( https://sites.google.com/site/diygeigercounter/gk-radmon ) however that would only give me CPM and µSv/h.

You need a concentrating system and a spectroscopic radiation measurement system to produce a signal with sufficient SNR.

I do have to complement the authors of this article. It presents the facts and leaves out political rhetoric and noise. I'm pleased with the title too; if the article were featured on a mainstream news site in the USA, it would have declared it as a definitive event and give a list of what products to buy from their advertisers.

I feel this vilification of the media is far overblown. Specifically: I cannot imagine that a quality news site (say the NY Times, Atlantic, or WSJ) would not mention such uncertainty. More easily provable: I challenge you to find a single article of about a disaster that includes unwarranted product recommendations (i. e. not "authorities are asking citizen to stock water and other necessities in preparation for the…

>I feel this vilification of the media is far overblown.

Trump's strategy of making everyone hyper-skeptical of the media is working then. When you think all news is fake you'll tend to stick you the sources that "you" think are truthful (and that match your preconceptions).

What about that news article that WaPo published about the guy who found some malware on his laptop and was blown out into this https://www.washingtonpost.com/world/national-security/russi... . I don't know how you could go from a virus on a laptop to "Russia is hacking into our power grid" unless you are being intentionally dishonest or have such an agenda that you jump at any scrap to make a story. That was terribl…

It's good they at least put a notice at the top but that doesn't excuse them. This is the kind of stuff Gawker does and was heavily criticized for, running a story without checking the facts because you want to be first or it fits your "narrative". I'm not sure what else it could be without it being much worse reason.

If you have a way to prevent things like this prior to their happening, I'm sure these newspapers (and many other industries) would love to hear it.

Until then, things like this will happen. Assuming all media is bad because of these incidents is silly.

Kind of off topic, but mind sharing how you molded such an amateur nuclear physics brain?

I suspect he was being sarcastic. The fact that a 90 amu atom doesn't yield 131 amu atoms when it decays doesn't require you to know about anything beyond conservation of mass.

Indeed.

The role of the camera is generally overrated, however there are certain characteristics that you only get with expensive full frame cameras such as the Canon EOS 5D Mark III he appears to be using: * very low noise * very shallow DOF * long bursts of rapid images * weather proofing (including cold) * improved dynamic range * high resolution (lets you crop the part you are interested in and retain good quality) There…

As someone who went to college for digital imaging technology I would say that's not strictly true, crop on a sensor actually has some advantages, for example if you have a 50 1.2 and you can't afford the 85 1.2 you can put the 50 on an APS-C, and in many instances that is cheaper than the second lens, none of the other points you made apply specifically to full frame cameras either. These are all shot on a MkII but…

A 50mm 1.2 lens on a Canon APS-C body has a full frame equivalent focal length of 80mm and a full frame equivalent aperture of f/1.9 — giving it the characteristics of a comparatively inexpensive lens.

In other words, your $1300 lens on a crop body will have comparable performance of a $350 lens on the full frame body.

Are you sure about that? When I profile it in chrome, about 50% of the time is spent in the garbage collector and "(program)". Randomly pausing the debugger most hits the ad code, which I think is what is causing the problem. It seems to be constantly loading and displaying the same ad over and over again, or something dumb along those lines. The irony is that there are only two small, mostly static adverts on the en…

program is native function calls, often poorly performing animations look like this, the connection is not immediately apparent because the calling function looks like it takes a disproportionately and innocently small amount of CPU time. Admittedly I did not check further so maybe i'm wrong, but that function is at the top of the list for the JavaScript code, if it's GC the connection is easier to establish because…

Typinganimationframe wasnt on the list for me. Just lots of calls using small amounts of time. Its the animation thats causing the gc and program time.

So provide them with expert advice for free? Do you think lawyers get this urge?

Lawyers don't decline to give legal advice for free just because they want paying, although they do, and fair enough. Law is a highly complex and recondite field, and a solid answer on any but the most trivial question requires nontrivial research to identify with confidence. Lawyers also have a professional guild to which to answer, and if they say something offhand which turns out to be erroneous in a way that brin…

'A highly complex and recondite field, and a solid answer on any but the most trivial question requires nontrivial research to identify with confidence.'

So very much like the problem identified here then?

I agree with your sentiment though.

How much does it cost for such a trip?

Looks like it is around 6000€, so pretty expensive but worth it? source: https://www.quarkexpeditions.com/gb/antarctic/expeditions/an...

Yes these sort of trips aren't cheap, but I still consider them good value for money to see corners of the world that are stunning and completely inaccessible otherwise. Note that it is possible to get significant discounts when there are sales (eg Black Friday) or last minute when they have spare cabins to fill. I've done a few other similar trips and I've never paid full price, including one to Antarctica where I managed to get nearly 70% off.
