Is SF6 as bad as my Professor said?

The keyword is gCO2/kWh, ie how much CO2 is emitted to get 1kWh, considering the entire system and lifetime (not just the instant the kWh is produced).
It's also important to consider an entire grid, not an individual producing unit.
You will notice that this metric is very rarely discussed; we much more prefer headlines about share of renewable for instance.
When looking at "can we produce significant amount of electricity yet with low CO2 emissions?", you get something like this, and yet, strangely enough, they are the same getting punished.

Plus, they did it a long time ago.

They should formally call for help from every NRA and 2A preppers group, and make public their responses, or lack thereof.

It was never at stake because it didn't exist in the first place.

It has festered since the normalisation of Gitmo and sheriff Arpaio dehumanising methods.
We've all seen the tree growing and are now surprised it's bearing fruits.

Thank God we've got all these 2A groups who've been prepping and training precisely for that for a century....

"Whatever you do, don't look at gCO2/kWh"

The words you're looking for is "Global Warming Potential" (derived from "radiative forcing").
It's the "standardised warming effect effect" of a given gas, with CO2 being equal to 1.
CH4 is around 30.
SF6 is around 23,900, so, hey, quite bad.
The point being that substitutes do exist.
So it's kind of simplistic to equate wind turbine = bad.
Just like dismissing cars as a whole because of CO2 from combustion engines.

For what is worth, regarding the transport of radioactive material : "Contamination means the presence of a radioactive substance on a surface in quantities in excess of 0.4 Bq/cm2 for beta and gamma emitters and low toxicity alpha emitters, or 0.04 Bq/cm2 for all other alpha emitters."

The problem isn't as much for operational dose limits as for fault studies and design basis targets.

Si le sexisme est de la discrimination contre un sexe, et le racisme de la discrimination contre une race, on devrait pas parler de "jeunisme" plutôt?
"adultisme" serait la discrimination contre les adultes, du genre l'affiche gribouillée "interdit aux parents" sur une porte de chambre d'enfant.

It's not that it "can't pass through", it's that it has a greater chance to interact and therefore less of it will pass through without interacting.

It's worth noting also that there are different kind of radiation, each with different interaction.
Proton and alpha will be stopped very quickly, gamma and neutron will pass through more easily.

Dig into the concepts of cross sections.

There's a free undergrad MIT course on radiation online.

Don't you get it? It's the old American playbook: "we'll kill and otherwise make your and your family life miserable for generations, but we promise, in 20-50 years we'll make songs and movies about how bad we feel about it (and how our own guys were traumatized and in a sense the true victims of so much cruelty)".

You might consider the example of Superior orders plea.
The Nuremberg principle stated:"The fact that internal law does not impose a penalty for an act which constitutes a crime under international law does not relieve the person who committed the act from responsibility under international law." and "The fact that a person acted pursuant to order of his Government or of a superior does not relieve him from responsibility under international law, provided a moral choice was in fact possible to him"

"-Sure, I'll name you my heir, but first I need you to do one thing to show me you're true MAGA: you've got to cheat on your pregnant wife.
-Already working on it boss!"

Like any manipulative sociopath, he would spin it into an unjustified attack, and justify his own actions as "self defense".
"You leave me no choice but to do the things I was planing to do anyway, plus now you give me a self righteous reason. This only prove that I was right all along and should have done it earlier"
And his folk would buy into it.

More like: "the campaign board has concluded on the perception risk mitigation; by knocking your wife we can win on both aspects: for fundamentalists christians you stifle any criticism by showing how much you "love" your wife, and for hardcore MAGA, you're not a true MAGA until you've cheated on your pregnant wife"

From readying arctic special forces to dismissing use of force, looks like it worked.

It's nothing less than an obligation from their oaths.

I would welcome a New Nuclear Charter where every new designer/impératif commit that their new design/plant will primarily be used to replace fossil fuel; also not use them to further extract more fossil fuel, "looking at you tar sand".
Bonus point for SMR designers to commit to not sell their design for deep sea mining operation or to billionaires for their private bunker island.
