In particular: "The most egregious of “Chernobyl” sensationalism is the depiction of radiation as contagious, like a virus. The scientist-hero played by Emily Watson physically drags away the pregnant wife of a Chernobyl firefighter dying from Acute Radiation Syndrome (ARS)."
It has been argued that high doses of radiation would contaminate the actual living person receiving them. This was definitely something that was considered to be true at the Chernobyl disaster time, as a wife of one of the Chernobyl firefighters found out -- she was not permitted to hug her husband in the hospital, and she tells that she was told the hospital rooms became contaminated after hosting the firefighters.
Since there is a contradiction with what was said earlier, I presumed that it would be quite possible for the firefighters to have inhaled radioactive particles.
However, I was wondering, under what levels of exposure to radiation or additional factors -- without actually having radioactive material as leftovers in/on him -- could a person be irradiated to the point that his body became dangerously radioactive to people around him?
Would it be possible to be so contaminated and remain alive for appreciable amount of time?
