It's the Sengoku Drivers probably. Why else would the researchers be wearing them?

As long as they hold the belts, their bodies are immune to the effects of Helheim.

Lose them and they may end up like poor Ryoji...

Having a natural immunity could work too. Some deadly diseases in human history like The Black Plague have been studied by scientists, only to discover that modern human immune systems can completely block out what once killed us centuries ago.

There are those with unusually strong immune systems, but until we get more intel, we should hold off on guessing.
