[ELI5] Why is it in media where a character receive a blast of radiation, all other characters immediately cease any rescue attempts?

Depending on the level of radiation received, at a certain point there's literally nothing to be done. There's no intervention, no treatment, no medicine, and no device that can save a person once they've been exposed to a lethal dose of radiation. Not only that, they may be highly radioactive as well depending upon what they were exposed to and how they were exposed. So if someone's certain to die, and nothing you do will change that or provide any comfort really, then you wouldn't use the resources of rescuers or risk exposing them to harm as well.
