The loss of ions in the slow extraction area of the SIS100 accelerator project at FAIR can be dangerous for the electronic equipment and fiber optics situated inside the tunnel and niches around. During the slow extraction lost ions irradiate the yoke of the quadrupole magnets and collimator and produce a neutrons flux, which can damage or make single event upset at the electronic devices. Also fiber optic cores fade under the action of irradiation. In the current work the investigation of the dose distribution and neutron fluxes, as well as the calculation of the lifetime of the electronics and fiber optics in different places of the tunnel have been done. By using these results the design of the niches and shielding is planned.
