Abstract: The present (or current) nuclear shielding is bulky and difficult to handle due to the reduced stopping power of the neutral radiations (X, gamma, n) in materials. It is proven that these radiations are reflecting at grazing incidence angles on special substrates called super-mirrors that contain nano-layers of various materials. The usage of nano-structures in an ordered manner or of nano-tubes may create inside the nano-structure the super-mirror reflection conditions and makes these nano-structures act like wave-guide for this neutral radiation driving it and turning at angles greater than 90 degrees requiring a total thickness a few microns only. The usage of ferro or piezo electric nano-structures generates a “shield” structure that has the wave-guides inside with the path dependent on a control voltage.
