The development of radiation protection conception for the SAD project (with participation of the LRB specialists) is finished now. It was carried out a big volume of calculations of radiation environment in the dwellings of the subcritical assembly building taking into consideration different radiation sources - 660 MeV proton losses within the beam transport line and magnet optic elements, leakage neutrons from the shield of the assembly active zone, leakage neutrons from the solid phasotron shield. On the grounds of obtained data the allocation of the radiation impact areas inside the SAD building at different modes of the installation operation was proposed. The calculation of the neutron dose rate in environment around the LNP phasotron, the estimation of the induced radioactivity of the equipment and in the magnet hall as well as the estimation of the atmospheric injection activity were done. The measurements of the leakage neutron dose spatial distribution at the SAD building site were carried out. The investigation of the neutron induced radioactivity of the phasotron border soil was don as well.

         The calculation and design of radiation shields againstneutronsfor mobile and stationary castom installations for identification hidden explosive and narcotic substances were constructed.

         The radiation detector responses study was continued.The calculation of the multisphere neutron spectrometer response functions at neutron energy to 20 MeV was ended [7]. The calculations of the X-rays detection efficiency for scintillation and Si-detectors were carried out.

         In the frame of the collaboration between Space Research Institute (Moscow) and the  JINR on the planet surface research programme the preliminary estimation of characteristics of the LEND device assigned for the Moon surface scanning was produced.

         Three radiobiological experiments at the nuclotron (with 480 MeV/n carbon nuclei and 1 GeV protons) as well as at the U400M (boron-11 nuclei with energy 37 MeV/n) were carried out in 2005. During the runs patterns of human blood lymphocytes and eye proteins were irradiated.
