Measuring equivalent doses to the Ionization inspection systems (Rapiscan-GaRDS)

Abstract

This study aims to measure accumulating equivalent dose to the radiological workers (operator) under inspection cars drivers and then compare with constrains of radiation exposure used by other countries which use these systems as a first step to put the local limitations. The last published version of IAEA (GSR. Part no. 3) in 2011 mentioned that using of these systems are forbidden only after prevented the obtaining the justifications of the regulatory body for each country, knowing that it is a modern practice in the world and until now there are no such limitations in most countries. Some red eye devices have been given to the number of truck drivers of petroleum transport products and instructed them to pass through the scan system with different speeds to measure the accumulating equivalent doses in the truck drivers under inspection, radiological workers, and general people. The results accumulated equivalent doses were compared with theory results of the systems and also with documented results in the operation manual. The results showed that the doses are within the limitations only in the commitment with limitation documented in the operation manual of system.
