[Godzilla KOTM] Why weren't the human spectators of the Godzilla-Ghidorah fight killed immediately by the Nuclear Pulse?

Some things to consider:
* According to Godzilla lore, he uses a radiation attack
* The charging radiation melted buildings and steel cranes, while the blast itself disintegrated Ghidorah's wings - which have elements of gold in them
* Cement has a melting point of around 1550°C and steel melts at around 1510°C, while gold starts melting at 1066°C. Concrete doesn't have a definite melting point, but quartz sand has a melting range of 1650°C
* Concrete starts experiencing structural damage at a dosage of 10 in the root of 19 rad per square centimeter

TL;DR: To do the damage shown in the film, Godzilla's charging temperature exceeded 1650°C and the radiation he generated was more than 10 decillion rad. His actual pulse greatly exceeded these stats.

So why didn't this immediately kill the humans watching the fight or at least crash their Osprey? Even if lead lined, nothing could even withstand Godzilla's charging!

Titans don't really seem to play by our understanding of the laws of physics... It's possible that Big G had a lot more control over the actual energy than one would expect. It looked like a wild and uncontrolled discharge, but like you said, if that had been the case there would have been a lot more collateral damage. Maybe the visual pulse wasn't 1-to-1 with the actual energy he was putting out? 

Alternatively it's a slow burn, and everyone within a hundred miles is going to be going Wade Wilson in a couple weeks.
