Our devices were built for safety. With more than 50 years of experience in X-ray technology, AS&E follows extraordinary safety procedures. And we take safety as seriously as we take security.
AS&E rigorously adheres to standards designed to govern X-ray scanners for security applications, including those of ANSI, EURATOM, and ICRP. AS&E also uses independent organizations to certify that its products meet the applicable radiation standards.
The X-ray dose delivered by all AS&E® systems is measured according to well-established guidelines and procedures described in the standards and recommendations from ANSI1, EURATOM2, and the ICRP3. Compliance with these standards is measured and confirmed by a number of independent third-party organizations. All of AS&E’s systems that are approved to scan people fall into the category described as “trivial” by radiation experts from the Health Physics Society4.
According to Dr. Dushyant Sahani, who specializes in radiology at the Massachusetts General Hospital, Boston, “To put things in perspective, the dosage that is delivered from these scanners, the risk is absolutely minuscule or trivial.” In addition to Sahani, the Centers for Disease Control, the FDA, and the American College of Radiology all state that airport security scans are no more risk than the radiation we’re all exposed to from natural sources, like soil or rock.
It’s important to keep in mind that all of us are exposed to ionizing radiation every day, from many parts of our environment, including the food we eat, the building materials used in our homes, and even from the altitude of the cities and towns in which we live. The radiation dose received from a Z Backscatter™ scanner should be considered in this context. To compare an effective dose, let’s look at a scan from the SmartCheck® HT personnel system. It is equivalent to:
- About half of one percent (0.5% or 1/200th) of the radiation dose received by the average person on any day of the year, much of which is from natural sources.
