Traditional techniques proved to be effective for decades; however, with the latest advances in technology, the intruder can implement more sophisticated methods to bypass inspection points control techniques. The present study provides an overview of the existing and developing techniques for non-intrusive inspection control, current research trends, and future challenges in the field. Both traditional and developing methods, techniques, and technologies were analyzed with the use of traditional and novel sensor types. Finally, it was concluded that the improvement of non-intrusive inspection experience could be gained with the additional use of novel types of sensors (such as biosensors) combined with traditional techniques (X-ray inspection).<\/jats:p>","DOI":"10.3390\/s22062121","type":"journal-article","created":{"date-parts":[[2022,3,10]],"date-time":"2022-03-10T02:10:35Z","timestamp":1646878235000},"page":"2121","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Application and Advances in Radiographic and Novel Technologies Used for Non-Intrusive Object Inspection"],"prefix":"10.3390","volume":"22","author":[{"given":"Dmytro","family":"Mamchur","sequence":"first","affiliation":[{"name":"Information Technologies Department, Turiba University, Graudu Street 68, LV-1058 Riga, Latvia"},{"name":"Computer Engineering and Electronics Department, Kremenchuk Mykhailo Ostrohradskyi National University, Pershotravneva 20, 39600 Kremenchuk, Ukraine"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4125-494X","authenticated-orcid":false,"given":"Janis","family":"Peksa","sequence":"additional","affiliation":[{"name":"Institute of Information Technology, Riga Technical University, Kalku Street 1, LV-1658 Riga, Latvia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3605-7351","authenticated-orcid":false,"given":"Soledad","family":"Le Clainche","sequence":"additional","affiliation":[{"name":"School of Aerospace Engineering, Universidad Polit\u00e9cnica de Madrid, 28040 Madrid, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6570-5499","authenticated-orcid":false,"given":"Ricardo","family":"Vinuesa","sequence":"additional","affiliation":[{"name":"FLOW, Engineering Mechanics, KTH Royal Institute of Technology, SE-100 44 Stockholm, Sweden"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"329","DOI":"10.1080\/08865655.2015.1066702","article-title":"Customs and Illegal Trade: Old Game\u2013New Rules","volume":"30","author":"Polner","year":"2015","journal-title":"J.
