[en] The paper presents the results on studying the radiation conditions caused by induced radioactivity of the accelerator units in the ring hall. The data on the induced radioactivity level just on the ring vacuum chamber are reported. Radiation conditions in the most characteristic areas of the hall are considered. The changes in time of the dose rate at the internal target and at the entrance to the hall are shown

[en] An adiabatic calorimeter for measuring the value of absorbed dose of mixed radiation generated by 70 GeV proton synchrotron is described. The calorimetric system consists of a working body (a core) and a shell (a screen). The calorimeter adiabaticity is provided by the absence of the core-shell heat exchange by maintaining the shell temperature equal to the core temperature and, consequently, the whole energy generated in the core goes for its heating. The work showed the possibility of carrying out the adiabatic calorimetric measurements of absorbed dose of secondary radiation generated by un accelerated proton beam under the conditions of alternating magnetic and electric fields at the IHEP proton synchrotron at the average dose rate not less than 5x10^-3 Wxkg^-1

[en] The information input and processing system in computer from radiation monitors of the IHEP neutrino channel is described. The software permitted: to obtain mean and integral values of radiation levels along the neutrino channel in a given period of time and a definite number of accelerator operation cycles; to carry out the estimation of the radiation situation along the neutrino channel on the solitary output of a beam into a channel; to obtain the results of data processing on a linear printing along with proton beam parameters averaged in this period of time. The preliminary measurement results on distribution of proton beam losses along the neutrino channel are given
