Years after the 2011 (Fukushima) disaster, a group of French nuclear
physicists wanted to see whether cesium-137, a radioactive isotope,
was more present in wines made after the disaster than those made
before.

The bad news: Some wines from after 2011 had twice as much radioactive
material.

The good news: The levels are still too low for you to worry about.

Wine’s cesium-137 levels after Fukushima are nothing compared with
what they used to be.

A few things spiked radioactive levels in the early 1950s. The first
thermonuclear weapon was tested by the US in 1952. Two years later,
the Castle Bravo test set off the largest thermonuclear device ever
detonated by the US.
