Detection X-ray systems detect contaminants by density difference As an x-ray penetrates a product, it loses some of its energy A dense area such as a contaminant will reduce the energy even further As the x-ray exits the product, it reaches the sensor - an array of photo-diodes that precisely measure the x-ray energy that reaches them The sensor converts the energy signal into a grey-scale image A high-speed computer scans the sensor at thousands of times per second and stores the individual signals It compares them to a dynamic value that delivers the maximum level of sensitivity and minimum level of false readings A contaminant is highlighted as a darker shade of grey than the product Effective x-ray inspection depends on the sophistication of data analysis. All LOMA machines comply with national emission and safety regulations. They should be notified of changes, additions and subtractions made to any plan. Are X-ray systems suitable for products with a variable density? The one-time installation cost can buy a sense of security "instead of investing in more longer-term strategies that are focused on people," Trump said. Skip to main content Skip to footer site map.

    Early X-Ray systems had reliability problems and were expensive.

    She hesitated to say that the school staff member would be "trained," but "they do go through some kind of proper familiarization process. X-Ray Inspection systems can also check for product intermarry to see missing or damaged products. The Quebec Unit, the city's version of school resource officers, also circulates between schools to keep an eye on things, and cameras monitor every common area.
