I've followed this channel for years and it's a good one to follow if you want to see a lot of on sight stuff of the plant and the surrounding area, although she hasn't posted in a while.

I'm glad they showed the New Safe Confinement at the end of the last episode, given that's sorta the book end of the event since that's the last thing needed to dismantle the reactor building. The readings around the plant went down by ten times apparently when they finally moved the new cover over the old sarcophagus.
The sarcophagus was set to expire in 2016 since it had a 30 year expected lifespan. By that time, there were holes in the roof and rain was getting in, and there was a partial roof collapse several years ago. Inside the reactor hall is still pretty radioactive obviously, but it's probably a 1/3 of what it was. They gotta remove the "Elephant's Foot" from the basement, which was the melted fuel that became a lava and it pooled a few levels under the reactor. It's eating away at the floor and is still a threat but not anything that would happen anytime soon.
It's not nearly as dangerous today and I think it's about a half hour that would give you a fatal dose. In 86, it would probably kill you in a minute or so.
