Jo, I suggest you switch your weapon to single fire mode. Burst is good for groups of enemies and dangerous foes like zerglings or dangerous and tough opponents like aliens. Just apply the pulse rifle.
As for radiation ... hmmm. Make sure you know what your grenades do. Same with ray guns. If you still feel tired, weary or have headache at some point drop all your unknown canisters. You can come back for them later. That should do it for now.
When you become radiated best thing is an item from Fallout which is present here too. It might pay to drink canisters in hopes of identifying it among your possessions.
Implants are a bit of a gamble. The worst thing is narcoleptor. It puts you periodically to sleep. Other bad implants are not that deadly. Still, I managed to survive quite a bit with it because my marines usually have some HP to take punishment with.
