Why 70 years, or why 1946? Tried Googling but didn't see answer. I had thought carbon dating was pretty inaccurate anyways, didn't think it worked on such small time scales. Maybe this is a joke that went over my head.
I wouldn't have guess such small amounts of radiation in the atmosphere would interfere with carbon dating, but I know literally nothing about how it works. Seems like solar radiation and such would be a bigger contributor?
