Calibrating characteristics of the radiation thickness gauge of the automated system for cleaning the cyclone inside walls from the fine wood dust deposits

Radionuclear technique for measuring the near wall deposit thickness is offered by the authors as a result of researching the process of the cyclone inside wall cleaning from the fine wood dust deposits. Descriptions of the characteristic and specific peculiarities of the devices, which operate on the radionuclear technique principles and main functions of the devices, which handle the signals of the radionuclear device in condition of necessary application of the sources with minimum radiation level are given.
