Summary: We consider an integral operator \(T\) whose kernel \(G(x,y)\) depends on the distance \(|x-y|\) and is unbounded as \(x\) and \(y\) (which are points in \(\mathbb{R}^n)\) approach each other. It is shown that \(T:E\to F\) continuously for certain choices of rearrangement invariant spaces \(E\) and \(F\). Special attention is paid to the case of Orlicz spaces.
