This is cool. It’s very small amounts.

The key issue is that they are making antimatter at CERN but the magnetic fields at CERN impede studying/analysing it.

Checking in with a nearby physicist, the amount is so small that even in the worse case it would be unlikely to set off a radiation detector.

In return for this sagesse, I was subjected to several witticisms on the detectable rate of decay in the bananas we have awaiting to be turned into banana bread.

I love that "banana for scale" is also applicable to radioactivity.

They're making such progress! It wasn't that long ago that storing antimatter for a few minutes was a big achievement, let alone transporting it

I was just about to post this! Now I really want to know if Data's neural network was banana powered.

"If one crunches the numbers (as they do in the original article), it turns out that bananas pop out a positron every 75 minutes or so."

From the Memory Alpha wiki:

He did not require sustenance, but occasionally ingested semi-organic nutrient suspension in a silicon-based liquid medium to lubricate his biofunctions. (TNG: "Deja Q") Though capable of consuming more traditional food and drink, Data had no sense of taste and therefore tended not to bother eating. (TNG: "Hero Worship")

So, you could probably derive some of the organic components from bananas, but generally no. He's not really banana-powered.
