Radiation damage to electronics in the Linac tunnel of the Next Linear Collider due to ionizing and non-ionizing effects has been estimated with detailed FLUKA simulations. Re- sults for total dose deposited in silicon and for displacement damage by neutrons, protons and charged pions are presented. It is shown that non-radiation-hard electronics could be severely damaged unless sufficiently shielded against radiation. A scenario is proposed in which the electronic components are located in niches in the beam tunnel wall which are shielded by layers of polyethylene.
