Measurement of angular distributions of intensity of gamma radiation in the zones of works on 'Shelter' stabilization

The procedures, designed for measuring angular distributions a gamma radiation from aggregations of radioactive materials located in object 'Shelter' are described. The first procedure is based on application of the original multidetector device DB1, permitting to get the data on an angular distribution in a complete solid angle (4 pi). The second procedure is based on application of the modernized dosimeter DKS-04 with the collimated detector. The main observed data on the angular distributions of intensity of gamma radiation in the zones of the works on 'Shelter' stabilization (the measurements have been carried out in frameworks of the exploratory design) are presented. 9 refs., 49 figs.
