Three of the casualties were reportedly delivered to a civilian hospital in Arkhangelsk, with two of them dying later. Although they were delivered naked, they apparently hadn't been sufficiently deconned - one of the fifty staff subsequently tested has been found with caesium-137 in their muscle tissue. The staff is furious with their superiors for not warning them to take precautions or being stuck with the military's wounded in the first place; the ward spent a few days in lockdown for decon and testing while the FSB were making the rounds with NDAs.

Sheepish semi-confirmation from official sources. Hospital staff demanded a testing regimen; 91 already tested, none found to emit radiation levels above "acceptable" for a human being (they were using a full-body ionizing radiation spectrographer).

There is no need to absorb Cs, it's enough good on its own.

So... no gammas, according to the Russian government itself?

Between the hype, the illiterate press and the rumours, everything in Russia gets the N-word.

Could this "pulse laser" be used on ISS to destroy or repel dangerous pieces of debris? Or even deorbit bigger pieces? Probably power requirements are quite high, but station could trickle-charge this hypothetical capacitor over the course of couple of days.

There, AFAIK, was such a proposal, but for an entirely different, international laser.

There were also proposals to refit the Russian military LADAR facility with an anti-junk laser broom; instead, its new biggest laser is being repurposed as a satellite blinder.

No supporting info on the main article: http://www.hisutton.com/Poseidon_Torpedo.html

Naturally, this contravenes every official statement on the nature of the test article this far; an argument some pages back seemed to not treat the wording as suggestive of a pumpjet; Sutton himself has worked to dismiss the claims of fantastically high underwater velocity.

Pavel Podvig is a treat. I'll populate an entire page with his retweets.

Comrade Major, I didn't write this.

...but since you insist, I know a good pizzeria on Kitai-Gorod.

For what it's worth, the photo of the container was titled Skif.jog or somesuch, and it's very different in size from the final article.

Common handling equipment for multiple families of doomsday weapons?

???

UDMH or non-volatile rad contamination?

Unsurprisingly, the residents of the Severodvinsk area are moderately radiation-savvy.

Maybe they just don't want the bums to try and sell the platform for scrap?  Then again, a little radiation or toxic waste doesn't seem like something that'd dissuade those...

I admit forgot about Poseidon, but if this was one of those, then what exploded? A torpedo could potentially run on a large RTG, and in fact that would be quieter than a reactor. In this case, the only explosive thing onboard a Poseidon should to be the warhead, and they wouldn't put that on a test article. It very clearly isn't supercavitating, and there's no reason for it to be. A supercavitating torpedo of that size would be very easily heard, and since sound travels faster in water, it'd only give the enemy early warning of its approach.

That’s a bigass nuke torpedo. 

Whoever designed it must’ve taken the inspiration from warhammer 40k.

The one in Kandalaksha in 2000 actually managed to get lethal rads from an RTG, which is a serious achievement.

Power density would be quite abysmal, and the design is inconsistent with "leaked" (big scare quotes) schematics.

This seems to be an increasing trend in Russian defence policy, from Schola Progenium to geneseed collection. It's not just a coat of arms.

[DDE]

Looks like another arms control mechanism is destined for the garbage bin.

This isn't a police procedural, you're not supposed to plead the Fifth.

(Obviously, an offtopic in this thread, but just on a nuke theme.)

Two more rad monitoring stations have paused uploading data to the network (on Chukotka and Altay). So, it's just a routine, nothing interesting.

True... what if it's the platform that runs on an RTG? Poseidon is supposed to be capable of being launched from platforms resting on sea bottom. This is something that looks suited for a "nuclear battery" application of an RTG, since they'd just need to keep electronics running to await a launch order.

Of course, that has even less reasons to explode than a Poseidon does.

[kerbiloid]

Poseidon probably should have both rtg and reactor, to wait and to run.
Also maybe a chemical starter, just4lulz.

(At least, I would do this in KSP.)

Spoiler

I would also add a Kerbal seat, but unlike the humans, Kerbal can stay for years on bottom.

The seabed Poseidon is one interpretation of Skif. I'm skeptical of it (in favour of an R-29 missile), primarily because of at least two, maybe three classes of submarine designed to carry it.

Don't forget a cage of chickens to keep it warm.

See the added spoiler, lol.

The rad monitoring stations data uploading is voluntary, the Foreign Ministry explained.

Well, an R-29 blowing up on the platform and taking out the RTG would certainly be a cause for concern, what with this being a hypergolic missile. 

[kerbiloid]

Two rad monitoring stations are back: in Yakutia (not mentioned before) and in Altay.

@DDE Would it be possible to produce moment tensor from the available seismic data ? Could it be used to infer the location of explosion that has happened ?

Doesn't seem to be much interest in that: the location isn't really in question.
