Weakest nuke-proof characters

[Guy1]

Weakest comic or fictional characters who could barely survive a Nuclear device? 2 scenarios:

1: The nuke in question is equivalent to WW2 era yield

2: Modern weapon

Rules: The character can brace themselves accordingly but cannot leave the area of affect. The explosion will occur within 20 feet of them. The character must be alive 1 hour after the initial detonation. If they succumb to their injuries in less than an hour, they are disqualified.

Claire Bennet. In one Alt Future at least she was Ground Zero of Sylar going Nuclear and actually woke up before Peter did, alive and whole, and yet she's also famous for going to pieces from pretty much anything.

Alternatively, Indiana Jones in a Refrigerator.

What if they die, but their injuries go away and they're back to normal within the hour?

I just want to know where Resurrection Man stands.
