Abstract
An automatic sampling method and facility are disclosed, by means of which multiple samples are obtained from a closed container filled with heterogeneous solid material. The sampling points are predetermined and well distributed on the container and the sampling position and depth in the container are selected by a special controller of the sampling system. The system can be operated at an open space for non-radioactive material. The obtained samples are collected and blended in a mixer for homogenization treatment to produce a final specimen for analytical measurement. The homogeneous specimen is well accepted for its representative character.
