Morphology
The meaning is directly compositional: 'radius' (distance from a center) combined with 'curvature' (measure of how a curve bends) yields the radius associated with the curve's curvature. Although a technical mathematical term, the 'X of Y' structure is transparent and commonly expressed similarly in other languages, so a B1 learner who knows the constituent words can infer the meaning.
Etymology
Radius of curvature comes from a simple picture: at a point on a bent line you can draw the circle that matches the curve, and the radius of that circle shows the amount of curvature — a small radius means a sharp bend and a large radius means a gentle turn. So, it measures 'how sharply a line bends' at that point.
