[Marvel] What's the deal with Carbonadium anyway?

AFAIK it was created by the USSR as an answer to Adamantium and it is more flexible but less durable (while still being effectively indestructible for all practical purposes).

For one thing, doesn't that make it superior to Adamantium?  Why doesn't everyone use that?  Yes, there is Carbonadium poisoning but Adamantium poisoning is a thing too (which makes me wonder what the deal was with Bullseye when he got some grafted onto his bones), right?

If the answer is that the techniques to make it were lost (and presumably that means all the Carbonadium swords out there were made in the past by the USSR or their allies), that brings me to another question:

I know that a Carbonadium sword can mess with Wolverine's healing factor (do Omega Red's tentacles?).  Why exactly is that?  Could Wolverine have survived having Carbonadium bound to his bones instead of Adamantium?  What about Feral Wolverine?

Problem 1: It's not so much normally poisonous as it's *radioactively poisonous*. Anyone using it would soon succumb to radiation poisoning without some other factor to protect them.

Problem 2: Only one device is known to consistently make it, and most of the world thinks that device, the Carbonadium Synthesizer, was destroyed.

Now about Wolverine: Omega Red's tentacles do disrupt healing factors, but at that point the life draining properties become a much more immediate problem for anyone caught in them.

The why is pretty simple- they're highly radioactive and are constantly damaging and destroying the DNA of cells while they are in contact with a victim. Healing factors require the cells to reprogram themselves on the fly to become what the body needs to heal, and it's difficult or impossible to do so while the instructions for that reprogramming are being blasted apart by subatomic particles.

Since Carbonadium damages healing factors, it's unlikely Wolverine (of any variation) could've survived the process that created his skeleton if they attempted to implant it. However, knowing the Weapon X program, there's a few corpses buried someplace on which they tried.
