That is not even close to feasible with today's level of technology, and will not be for quite some time.

well, maybe wearables that provide some sort of internal visual scans. But with CT scans delivering 70 times the radiation of a typical x-ray, I think I'd prefer not wearing a portable chernobyl.

Maybe a wearable ultrasound instead?

edit: after a little informal side-searching after posting this, I've learned that people working at Chernobyl, not in the reactor directly, but elsewhere in the sprawling site received anywhere from 1 to 100 CT scans worth of radiation. The firefighters that were on the roof received anywhere from 100 to 1,600 CT scans worth of radiation.
