No. I would, based on the long history of the Green Hulk who has always, supposedly, emitted radiation, assume there is no long-term radiation danger of being in the presence of the Hulk if you were a normal human being (aside from the danger of people trying to kill, restrain, destroy, imprison or erradicate the Hulk and his attendant response to such threats). The idea was likely born in the very first issue of the Incredible Hulk when a Geiger counter on a table nearby went crazy as Banner transformed into the Hulk.
EDIT: I had an epipheny. What if any or all Hulks only emitted radiation DURING their transformation into their Hulked out form or during moments of supreme exertion? This would neatly explain why no one dies from radiation poisoning while they are out looking for bad guys or waiting onboard a Quinjet. A burst of radiation, mass is exchanged from that mysterious realm where it sits waiting to be added to their bodies, and then the door is closed; poof! Radiation-free Hulk.
Early Hulk Transformation, Geiger Counter Goes Wild
The premise for the radiation emitted by either the Green Hulk (gamma radiation) or the Red Hulk (infrared radiation) has never been effectively quantified by the writers/editors of Marvel Comics. Nor has anyone been said to have died as a direct result of Hulk-emitted radiation.
The underlying phenomenon which is responsible for creating any Hulk has never been comprehensively explained by the Marvel Universe. Completely overlooked has been the nature of potential side-effects of the Hulk's condition. These side-effects would include the Red Hulk but curiously does not include any of the female Hulks.
It was mentioned in an offhand manner, the Hulk emitted gamma radiation during the days of the Savage Hulk. This was supposedly how General "Thunderbolt" Ross, was said to have found the Hulk with sensitive "gamma-ray scanning equipment".
Since it was written by a non-scientist, no mention of the actual level of radioactivity, no mention of the source of the radioactivity, or the rational for WHY the Hulk emitted enough radioactivity to be able to be detected with any long-range scientific device.
Adding insult to injury, the question of why the radiation emitted by the Hulk, which is supposed to be Gamma radiation, has not had any long-term effect on anyone who has spent time with the Hulk.
Given the Red Hulk's emission of infrared radiation (think hot asphalt in the summer or a powerful space heater) it might be possible for his touch to be unpleasant or even burn a normal human. This would be a marked difference from the Green Hulk whose radiation has always been considered just above the quality of background radiation except when he was exerting his powers.
This list of normal humans who would have been affected would have included long-time "Companion to Champions" Rick Jones who spent years with the savage and unintelligent Hulk. Betty Ross, former girlfriend and eventual wife to Bruce Banner also spent much of her time with the Hulk as well. Hawkeye, Captain America, Black Panther, and the Wasp were also early associates of the Hulk.
Since no writer has ever used the premise of "Hulk-emitted radiation" as anything other than a plot device, I would attribute it as a "special effect" to use Hero Game's Champion RPG language. It is a phenomenon which can be used for story-telling but has no real effect on anyone who participates in the character's life. As a caveat, I remind you if a writer WANTS it to have an effect it will. Hulk-emitted radiation was responsible for turning Ben Grimm back to his human form in Fantastic Four, Vol. 1, #167. The effect lasts until Fantastic Four, #175.
Hulk-emitted radiation transforms the Thing back into Ben Grimm. Take that, Reed Richards!
- Yes, it can help people find the character, if they have the right equipment, but it does not cause radiation poisoning in any of the character's friends. As a curious note, no female Hulk emits radiation of any kind, nor are they more affected by radiations either. I attribute it to their simply being less powerful that the male Hulks (and correspondingly less disadvantaged).
