Same with me haha.

Edit: just did a quick search and couldn’t find anything explicitly about radiation protection. But he did defeat some creature that was feeding on the Earth’s uranium mines and potentially power plants?

Also it seems like the suits only have a small window of active time before they have to find another host or something. So maybe the radiation wouldn’t matter on that short time scale.

I’m getting all this from a 5 minute search, so if anyone knows more than my shaky ramblings, please correct me.

Interesting read though. Makes me want to watch some old Ultraman.
