They are flea beetles, which make small holes in the leaves. Their tiny white grubs feed in the soil, so hoe-ing around your radishes will expose these to birds etc.

If they are causing a problem, then carefully (or they will hop away) spray with Bayers Fruit & Veg Pest Control, and then cover the crop with fine mesh or fleece to stop more arriving
