New Generation of the Portable Radiographic Equipment

A. S. Dekopov, S. V. Mikhailov, I. A. Budanov, V. G. Firstov

Portable radiographic equipment used in different industries within Russian Federation as a main NDT instrument is considerably out-of-date and does not meet the requirements of international standards. Replacement is necessary, and capabilities of new equipment should be considerably wider. Creation of radiographic equipment of new generation is accompanied by transformation of conceptual engineering solutions that improve structural, technological and operational characteristics of products.
Gamma-ray flaw detectors made by leading Russian manufacturers are presented for the research. Conceptual solutions, optimization and synthesis matters, reconstruction and computer engineering of important equipment components are analyzed. The constructional variety of serial 75Se и 192Ir isotopes is used as radiation flaw detection instruments.
Comparative characteristics of portable equipment constructional variety were presented for analysis and estimation of improvement possibilities for portable radiographic equipment. The innovation model of a portable emitter head equipped with high active (300 Cu) 192Ir isotopes has been proposed for consideration. It was created by computer-aided 3D modelling.
The optimality factor has been offered as a comparative parameter for estimation how the portable equipment meets customers’ requirements.
