To start there's triage. Go away and come back for cancer screening every five years. Stay here and we treat you. You're toast here's some painkillers. In between there's a wide mix of removing the cause and repairing the damage. This almost seems too obvious but there's obvious recent surface decontamination, wash it off. A test tube in the lab shattered, well get it all off you first of all. Only a step past that, if you chug heavy water you'll be encouraged to drink tap water to pee out the heavy water. Likewise if you ate something contaminated an hour or a day ago they'll give you stuff to make your digestive system explode out both ends. I donno if they'd feed you an expectorant for inhalation. There's no point if the exposure was months ago of course. There are peculiar specific treatments if you've been recently exposed to iodine isotopes from a bomb or very major plant accident they can flood your system with zero radioactivity clean iodine to convince your body to pee out 99% of your intake rather than adsorbing 100% of the bad stuff into your thyroid. Its like reducing your exposure by a factor of 100 just by popping some pills. There are other isotopes like that I can't remember. If you were doing radioactive labeling experiments obviously they'd flood your body with unlabeled clean stuff to make you pee the glowing stuff out. If its a bone-seeker there are mineral chleation treatments that are very hard on the skeleton but you'll pee out those isotopes which is better than having them irradiate you from the inside for decades. If you wipe out your bone marrow you're screwed unless you get a bone marrow transplant. In the short term they could pump units of blood into you. This works better if there's one victim per hospital than if there's an entire Japanese city and the hospital was vaporized, which is why not too much was done along these lines at the end of WWII. Similar to the above paragraph if you wipe out your digestive tract alongside 100K neighbors there's not much the hospitals can do, but if it was an unfortunate lab accident, you might be kept alive via IV until recovery. If its a surface burn I'm not sure what they'd do WRT preventative skin cancer, maybe skin graft it on general principles or wait and watch and see if a tumor forms. Obviously there's antibiotic treatment.
