Can anything about this? Every time I grow them they get eaten by something. I am guessing it's flea beetles.

I only grow radishes in containers now, up on a bench, I lose them sown direct in the ground, yes, flea beetle I'm sure. They don't seem to find them up high, though.
A physical barrier such as enviromesh or even an old net curtain will protect them or as small has said in a container about 2ft off the ground.
Brushing the plants with sticky fly-trap sheets can decimate the flea beetles - just leave the cover on the first 2 cm so it doesn't actually stick to the leaves. They jump randomly so quick passes after they move back can be very effective.
Lawrence D Hills attached his to a pole with tall wheels either side that bounce the bugs back to the sticky (you could use old LPs) - quicker and less bending. Perspex wheels would be even better - I think the bugs fear moving shadows.
Cheers.
I have mine in a pallet topper, with another one on top of it and it seems to keep them away... like carrot flies I think they stay close to the ground...
I've given up radishes! Flea beetles win every time!
