Question: Why was 1950 used as a standard year for carbon dating?

The year 1950 was chosen because it was the standard astronomical epoch at that time. It also marked the publication of the first radiocarbon dates in December 1949, and 1950 also antedates large scale atmospheric testing of nuclear weapons, which altered the global ratio of carbon-14 to carbon-12.

Why cant we use carbon-14 to date objects older than 50000 years?
