Radiation surged from you’ll die within weeks to you’ll die within hours but after some minutes you won’t be in working condition anyway.
They are gonna have to either wait for things to cool down, send in robots, or just send in wave after wave. It isn’t like nuclear technicians grow on trees either.
I heard somewhere - maybe Fox News - that they’re considering cooling the rods via channeling sea-water from helicopters. Not exactly sure how this works, or whether that will lesson radiation exposure.
