If you’re a TV junkie, there’s a good chance you’ve seen Chernobyl, HBO’s show about the 1986 nuclear disaster of the same name. It shows, in horrifying detail, how the meltdown and explosion of part of the Chernobyl nuclear power plant spewed massive amounts of radiation from radioactive elements and isotopes into the atmosphere. How that radiation poisoned first responders and citizens of the nearby cities of Pripyat and Chernobyl. How, for some, their bodies absorbed lethal doses of that radiation within minutes, killing them in mere months; for others, the damage played out more slowly over years.
