Whaaat? If this happened in the mid 40's I'd forgive it but this was the 80's they had to know it was a dangerous move...
Radiation is like fire when it comes to use, it is in fact dangerous but only if not used intelligently and diligently. If our "caveman" ancestors where to do with fire what we do with fission/ radiation we wouldn't be typing on this forum, I'm sure some of our paleolithic ancestors rallied against fire in some way, lol. "Fire burn, it bad, no fire!" "No! Fire good, cook meat, taste goood" then steam engines happened ._. (that's how it progressed right?).
And that's why hungry nodes eat you! A cave man liked cooked meat and then steam engines and then other stuff.
