Hazards and risks of non-destructive radiography method for the environment

In this paper, the effect of radiation hazards on the environment while using the non-destructive radiography method was investigated. The research was carried out by measuring the radiation amounts at 0.5 and 2 m distance from the exposure container with radioactive iridium-192 isotope used for tests with the radiography method. The tests were carried out in different positions in relation to the protective bunkers used in the company STSI Ltd. (Zagreb, Croatia) to reduce the radiation emission of the used radioactive isotope. The effectiveness of the protective bunkers in terms of reducing radiation in the environment is determined. In addition to examining the effects and hazards of radiation, the procedure for proper disposal of hazardous and non-hazardous waste generated by the non-destructive radiography method is described. Research has shown that the storage of exposure containers with radioactive iridium-192 isotope in the large protective bunker and the mini-bunker contributes to the improvement of environmental and personnel protection. The disposal of hazardous and non-hazardous waste after testing with the non-destructive radiography method has also proven to be of enormous importance for environmental protection.
