Estimation of the radiation environment and the shielding aspect for the Point2 area of the LHC

The estimation of the radiation environment for the POINT2 of the LHC, where it is planned to locate the ALICE detector, is presented. The dose level and neutron fluences have been studied in the FLUKA-95 and FLUKA-96 framework. The radiation levels have been investigated in the experimental cavern UX25 region, in the machine by-pass areas UL24, US25, UL26 and in the area of the counting rooms PX24. The radiation environment has been studied for two points of accidental beam losses. The dose level in the region of the counting rooms is lower than the recommended CERN limit 50mSv. The radiation level behind the access shielding at the air-duct chicane is not higher than 10mSv that is also appropriated for the use of this area as a public area. A more complicated situation is in the machine by-pass region UL24. The dose level in the tunnel is a few hundreds of mSv as a consequence of a rather small thickness of the separating wall between the shaft and the tunnel (near 1 m). The decrease of the radiation level in this region could be achieved by increasing the wall or the beam pipe shielding thicknesses. The latter is more preferable as a cheaper variant
