Radiation is definitely creepy and poorly understood. There was a great video by the Veritasium guy on it: [VIDEO] Punch line, you definitely wanna stay away from ciggarettes if you don't like radiation. There's also this crazy woman (I think she's German?) who likes to go play with radiation sources. She has the most dead pan voice that barely changes except to possibly register some excitement when she finds a particularly hot source of radiation. She has a bunch of videos exploring Chernobyl. It's quite interesting for example to watch her pick apart dirt to find the single hot particle: [LINK]

One of his other videos describes the people who are most exposed to radiation. The answer shocked me: [VIDEO]

The amount of radiation you receive during a regular flight is quite small, and more than you would receive on a supersonic flight: [VIDEO]
