Radio vs Radiation Protection

[Butterlord]

There's two upgrades I can get for my armor; one is called Static Field Generator and it gives 15% radio protection, which raises my radiation protection stat.
The other is called lead container which says it gives 15% radiation protection, but doesen't raise that stat. But that description says it's designed to counter against artifacts?
Has anyone tested either of these? They seem like they do the same exact thing. Doesen't radiation protection already raise protection against artifacts? Does Lead container have some invisible stats that are useful only for mitigating artifacts?
Worded very poorly and I'm utterly confused now

'Lead Container'' makes one of your artifact slots completely negate the inserted artifact's radiation.

Yeah I noticed it now, the slot turns green. I didn't get how the negating worked, they should just add an annotation to the description saying
-Nullifies radiation of one Artifact Slot

Always go with the lead containers if it’s an option, as said above it totally negates any radiation from artifacts in that slot highlighted green
