I hate to say it because so much of this show was actually really excellent and accurate but in the Chernobyl miniseries they totally did the “radiation is contagious” thing and it is just not true.

Things and people that are irradiated/hit by radiation in a situation like a reactor failure or contact with radioactive waste do not become radioactive. They can have radioactive particles on their clothing/skin or inside their body if they have ingested/inhaled radioactive material, but they are not emitting radiation themselves. Furthermore, a thin sheet of paper or cloth will stop the kind of radioactivity that would be emitted by such material, if it is on the outside of a person’s body.

Anyways the point is that the woman whose husband was dying of radiation poisoning and then she went in and spent time with him did not lose her baby because she spent time with him. That’s just not how it works.

Lots of environmental contamination-related stuff in movies is inaccurate but that one is the most recent I can think of.
