> In March 2018, police in Ankara seized a whopping 1.4 kilograms (3.1 pounds) of a substance, believed to be Californium, in a car following a tipoff. That time, however, the substance turned out to be organic with no nuclear or radioactive properties.
That's a strange way of saying they seized "a whopping 1.4 kilograms" of nothing. Kind of makes you question the merits of this story/seizure.
Least of all since them seizing the wrong thing a second time seems far more likely than someone driving around with $72M worth of a rare substance which can only be made in two places on earth (neither of which are Turkey).
One well known incident involved 91-272 kg of enriched Uranium going missing: https://en.wikipedia.org/wiki/The_Apollo_Affair
That's preposterous. Californium is not naturally occurring and costs tens of $M per gram to produce. Anyone who paid attention in high school should see big flashing alarms when reading a claim like that.
1.4 kg of Cf-252 would however emit something like 4e15 neutrons per second and 1.2kW (I first thought it was 700kW) of decay heat. Glowing and evaporation would be rather likely.
1.4 kg is 1.4e9 micrograms and as per [1] "one microgram emits 170 million neutrons per minute" will emit 1.4e9 * 1.7e8 / 60 = 4e15 neutrons per second. Decays of Cf-252 have a high neutron multiplicity, about 3.7 per decay, so the neutron came from 1.1e15 decays per second. Most of those (> 95%) came from the decat Cf-252 -> Cm-248. The masses of those two isotopes is 252.081626 and 248.072349 atomic mass units respectively, as per [2] and [3]. An alpha nucleus of 4.001506179127 u is also produced. (If forgot about that one, vaastly overestimating the decay heat.) A mass loss of 7.77e-3 u is equivalent to the release of 7.77e-3 * 0.9314941 GeV / u = 7.2 MeV. Each MeV is 1.60e-13 J. So in total we get 1.1e15 decays per second * 7.2 MeV per decay * 1.60e-13 J / MeV = 1.2 J/s = 1.2 kW. If you forget that the alpha nucleus exists you over estimate the mass loss by a factor 500 and get a decay power of 700kW...

But to be honest I am not sure if it is worthwhile to keep fixing bugs in this estimate. We know several good reason why there is no 1.4kg of Californium anywhere.
"According to Monday's NTV article, the suspects were reportedly in possession of a cache of Californium weighing 1.441 kilograms that they planned to sell for $72 million on the black market."
So, back in 2018, suspects were trying to sell 1.4 kg of a substance claimed to be Californium for $72 million.
Now, in 2019, suspects were trying to sell a mere 18.1 grams of a substance claimed to be Californium, again, for $72 million.
I am trying to imagine a gang of schmucks still trying to sell baking soda as Californium but now they adjusted the price to be more realistic.
So it seems that the Turks have seized about 66 years of production.
Or we have lost some information in the reporting. Possibly this is 18 grams of something that has tested positive for californium. That is different than 18 grams of pure californium. I'm not sure what testing they did, but i doubt they verified every atom.
There is likely a large amount of, for lack of the correct word, filler. When dealing with very precious substances it is not unusual to combine them with other easily removed and inert material to facilitate handling. When dealing with nuclear material, this reduction in the density of the radioactive stuff is a significant safety advantage. This could be 1% or less californium and 99+% filler ... still a significant find but not evidence of a clandestine production line.
This is from the last year and even has photos: http://www.hurriyet.com.tr/gundem/ankarada-nukleer-madde-ope...
Does this look like a Californium to you?
Here is the same "news" from the last year with pictures of the siezed Californium: http://www.hurriyet.com.tr/gundem/ankarada-nukleer-madde-ope...
This "news" pops up every once in awhile, it can be Californium but it can be some exotic phosphorus too. I guess it depends on the creative mood of the journalist.
I flagged this.
Is it a stretch to believe that Israeli and Turkish security services are in contact with each other ... Despite headlined animosity between the 2 countries?

Here's how a container suitable for safe transportation of _one_ gram of californium looks like: https://en.wikipedia.org/wiki/Californium#/media/File:CfShie...

I probably wouldn't care about the crash risk: if the cleanup crew is decontaminating a border crossing down south, I can get through up north with the other 1g.
Also, if the mule dies more than 72hrs later, I don't have to bother disposing of the mule.
If you publish the airport thriller, I declare my interest (c)
Regarding that airport thriller -- you can't bring any nuclear materials (particularly neutron emitters) through any major airport, they are all equipped with radiation detectors and neutron detectors, specifically to prevent that.
I do know a thing or two about nuclear forensics; unfortunately, I do not have any talent for writing fiction, so this thriller is not coming anytime soon. :)
Here is how you transport Californium-252
https://en.wikipedia.org/wiki/Californium#/media/File:CfShie...
A giant flask filled with polyethylene or water (lead won't work). That's for 1 gram only!
18 grams is just a ridiculous amount. I suspect it is not Californium-252 but another isotope (251?) or maybe not Californium at all.
But yeah it is the most expensive commercially produced substance currently. And smuggling it would make sense from that point of view. However being bombarded by deadly neutrons while handling it, probably ensures you won't be doing it for long.
That's a funny way of saying that we had interviews from the general that ordered the destruction of the program that all WMD had been destroyed after the Iran-Iraq war.[1]
I'd add that counter-evidence of continuance was strong if you're going to include that at all.

Does any one have a real idea to denuclearize rogue nations (N. Korea, Iran, Pakistan, etc.)? All I've seen is both the Trump and Obama administrations saying very nicely "please, please denuclearize" and imposing sanctions. Problem being, bad nations don't care about their citizens. Could some one please propose a method to force denuclearization by an unwilling nation? Or at least prevent them getting more?

pakistan does present a bit of a problem for the rest of the world. they have over a hundred nukes and a very tense relationship with their neighbor, india. it's somewhat unstable and ISI has had some questionable (to say the least) dealings with terrorist groups. definitely not a combination that makes other countries very comfortable.
that said, there are some legitimate concerns about the pakistani nuclear arsenal. the pakistani government has been either unable or unwilling to suppress the extremist militias inside its borders. it's not unreasonable to fear that these people might be able to steal a nuke. if an american or french nuke is used, it is almost certainly by the order of a democratically elected president. doesn't make much difference to the people who would die, but it's a much less destabilizing situation.
It still terrifies me, when I think of it. But far less so, for good reason or not.
(North Korea spends ~22% of their GDP on their military.)
This one was easy -- californium is the among the most intensive neutron sources, and 18g is a _huge_ amount of it. Any neutron detector worthy of its name should have raised the alarm.

I guess the cost of uprated springs is worth it, to the dedicated smuggler.
Shielding from neutron radiation usually involves thick and heavy layers of lead.
P.S. you can't build a nuclear weapon out of californium, at all. To achieve the nuclear explosion, you need to assemble the supercritical configuration (minimum necessary k_eff about 1.53 for plutonium) without any stray neutrons leading to premature initiation, then, at the precise moment, inject neutrons in the system (even a single neutron is enough) to start the runaway chain reaction. Californium excels at spontaneous fission; there are so many neutrons in the system at any time, that premature initiation is guaranteed.
I imagine a big problem with trying to build a bomb is that the neutron emission will make assembling and transporting the bomb extremely difficult.
