According to the current ICRP Recommendations, the principles of justification, optimization, and dose limitation for the planned exposure situations are directly applicable to the use of ionizing radiation in the security screening. The use of different X-ray inspection systems is carried out in some States and prohibited in others, and there are no published regulatory decisions on the formal justification of this type of practice. The decision for the use of X-rays involving human imaging for the security screening shall be justified by the government. The aim of this paper is to present the quantitative assessment of the radiation detriments and the expected benefits of a designed screening system, as well as the analysis of the measurements performed to demonstrate the respect of the dose constraints for the members of the public and the conformity with the IAEA recommendations and the applicable standards.
