X-Ray Screening Technology (xrayscreening.com) is an independent reference resource focused on the systems, standards, and operational practices behind X-ray and complementary screening technologies. The site exists to give a single, durable reading point for material that is otherwise scattered across regulatory bulletins, vendor datasheets, and trade press.
Who the site is for
The audience is anyone who needs a working understanding of how screening systems are built, tested, deployed, and regulated. Typical readers include:
- Aviation security and cargo screening personnel and the supervisors who train them
- Industrial NDT (non-destructive testing) engineers, quality teams, and procurement staff evaluating radiographic equipment
- Health physicists, radiation safety officers, and regulatory specialists who interact with cabinet X-ray systems
- Researchers, students, and journalists looking for a neutral, sourced overview of an otherwise specialised field
- Travelers and members of the public who want plain-language answers about radiation exposure and what airport screening actually does
What the site covers
Coverage is organised around the major application domains of X-ray screening:
- Airport security screening — checkpoint baggage X-ray, computed tomography, body scanners, and TSA operational protocols.
- Cargo and freight inspection — air cargo screening, maritime container scanning, LINAC-based systems, and customs programmes such as the Container Security Initiative.
- Industrial NDT — radiographic testing for welds, castings, composites, and aerospace components.
- Radiation safety — evidence-based answers about exposure, equipment leakage limits, and worker protection.
- Regulations and compliance — TSA, FDA, NRC, OSHA, ICAO, and ECAC frameworks.
- Training and certification — operator pathways, recurrent training, and threat image projection programmes.
- Equipment database and the technical glossary for quick reference.
Editorial approach
The site is written as a reference work rather than as commentary or news. Articles favour specifications, regulatory citations, and standardised terminology over opinion. Where ranges of values are given (energies, penetration depths, throughput, dose), they reflect the typical operating envelope of certified equipment in routine deployment, not a single vendor's marketing figures.
Three rules guide what makes it onto the site:
- Verifiability. Claims trace back to published standards, regulator publications, peer-reviewed literature, or widely accepted industry practice. Where exact figures vary by jurisdiction or system, ranges and qualifications are used rather than a single rounded number.
- Independence. The site has no commercial relationship with the equipment manufacturers, training providers, or government agencies it discusses. References to specific systems are descriptive, not promotional.
- Currency. Substantive pages carry a "Last reviewed" date so readers can judge whether the material has been re-checked recently. Regulatory and certification details change, and the date is the honest signal of when the page was last walked through.
How the content is produced
Pages are researched against primary sources first — TSA directives, FDA 21 CFR 1020.40, NRC guidance, ICAO Annex 17, ASTM and ANSI standards, ECAC technical documents — and then cross-checked against well-established industry references. Numerical specifications are cited as ranges where vendors and certification programmes publish overlapping but non-identical values.
Drafts are reviewed for technical accuracy before publication, and pages with regulatory content are revisited periodically to catch superseded standards or renamed programmes. The site does not publish breaking news, vendor announcements, or roundups; the format is reference material that should still be useful months or years after the publication date.
What the site is not
X-Ray Screening Technology is not affiliated with any government agency, including the Transportation Security Administration, the Department of Homeland Security, the Food and Drug Administration, the Nuclear Regulatory Commission, the International Civil Aviation Organization, or the European Civil Aviation Conference. References to these bodies are descriptive.
The site does not provide professional advice. It does not certify equipment, license operators, or perform radiation safety assessments. Readers making operational decisions — whether procuring equipment, designing a shielded facility, or interpreting a regulation — should consult qualified professionals and current primary sources. See the full disclaimer for the complete statement.
Contact and corrections
Corrections, clarifications, and questions about coverage are welcome. The contact page lists the current channel. If you spot an outdated regulatory reference or a specification that no longer matches current practice, please flag it — corrections are folded into the next page review.
