[Star Trek] How does the United Federation of Planets deal with Chernobyl & similar radioactive zones?
gpt
Transporters make situations like Chernobyl almost trivial to deal with. The bulk of the hazardous material - already contained within the Sarcophagus and New Shelter - can simply be transported away (either to a prepared safe location, or converted to energy and purged entirely).

As for the fallout and contamination around the exclusion zone already; deploying an array of sensors and transport enhancers would allow them to slowly identify and filter even trace amounts of radioactive material out of the soil.

The main hurdle is where radioactive material has already being incorporated into organic life, but between Starfleet's medical transporters and other treatments, that too could be dealt with given time.

A coordinated effort by the Federation could likely render the Chernobyl Exclusion Zone safe for human habitation in a matter of weeks. There are already a handful of people still living there, and it has become a sort of accidental wildlife preserve in the years since the incident.
