We published several papers explaining how these crystals produce X-rays and electron beams, and they're very efficient in doing this. So using low-energy X-rays or low-energy electron beams - by which I mean similar to the energies that are used currently in medical imaging rather than treatment - we can produce a really high dose of electrons that can penetrate a very thin layer of the skin. If such a device can produce high enough dose, then we can possibly use it for cancer treatment - and we're not far from this goal.
