Design and operation based analysis and risk assessment in industrial radiography practice in India

Abstract

The present study was conducted for risk analysis and newlineassessment in the industrial radiography practice in India, for both, the safety newlinecomponents i.e. design of the radiography devices and for operational safety. Both newlinethese aspects have been analyzed in detail to identify the areas which require newlineinterventions for improvement of overall radiation safety in the practice. Failure newlineModes and Effects Analysis (FMEA) methodology has been utilized for design newlinebased risk assessment of industrial radiography devices. While, Operational risk assessment has been carried out using the Probabilistic Safety Assessment (PSA) newlinemethodology. The present research work involves incorporation of various expertise from the newlinefield of industrial radiography, such as radiological safety officers from operating newlineorganizations, manufacturers and suppliers of the radiography devices, maintenance personnel, and radiation safety regulators. Data required for the analysis was newlinegenerated through various channels, such as conducting two rounds of Delphi newlinesurvey, field inspections of industrial radiography devices and several meetings newlinewith various stakeholders.The present work through the Failure Modes and Effect Analysis based risk newlineassessment for the existing design of the radiography devices identifies six failure newlinemodes of the exposure device, which have risk priority numbers in the range of 100 newlineto 500, where corrective actions are required to be recommended. newline
