Electronics, especially weakly shielded and protected, easily could be damaged with EMI, but that EMI will do nothing for human. Humans are very resistant to all that elcetromagnetic things.

Outer belt is even less dangerous. They are really nothing and all that crap about enormous danger of van Allen belts is just another shitty scare tale to enshure humans will stay on Earth.

There is absolutely nothing impossible in Moon landing and interplanetary flights. The real question is why we still sitting on Earth.
