All we know so far is what he has displayed in the films (both Hulk and The Incredible Hulk).

Hulk: Super-strength, speed, endurance, accelerated healing, leaping abilities, and it's said that his strength rises as his anger rises over regular levels, so it's likely all these other abilities will increase as well, and he did get bigger as he got angrier.

The Incredible Hulk: Super-strength, speed, endurance, some degree of accelerated healing, leaping abilities.

Nowhere is it stated in either film that he has achieved immortality or increased longevity. Also, it doesn't seem that either incarnation of the Hulk generated any gamma radiation; they just got angry, changed, caused destruction, and then changed back to normal.
