1) Tony Stark had help in building that clunky first Iron Man suit. Not the high-tech armors he then wore and wears. Neither other stuff like the repulsor technology, numerous advanced softwares, satellites, Mandroids, and a long etc.

2) Mister Fantastic has created a wide variety of inventions. Doom's more like the one who fights about their intelligence, Reed is good with making portals to other dimensions and stuff like that. Doom also created the first working time machine in the Marvel Universe. I wouldn't also say that becuase they fight over their intelligence they're less smart.

3) Bombs are tested remotely. For a reason numerous deserted islands were used to test atomic bombs decades ago. Also, not only he DID fire it, but the radiation wouldn't have created an army of Hulks, because the rest of the people were far enough. He got near it in order to save Rick Jone's life.

In my opinion, the smartest person on the Earth of the Marvel Universe is either Tony Stark, as not only was he already really smart, but the R.T. node in his chest incresed his intelligence to super human levels, or Reed Richards.
