Drive Through
Z Portal® for Trucks & Cargo
Buses and trucks drive through. Threats and contraband are stopped in their tracks.
Don’t let its compact design fool you: the Z Portal drive-through inspection system is designed to scan large trucks, buses, and cargo containers. Its Z Backscatter™ imaging provides photo-like images from the top and sides simultaneously—and quickly highlights organic threats and contraband, such as stowaways, explosives, drugs, and alcohol.
The Z Portal system is as efficient as it is thorough: This high-throughput screening gateway can scan 80 trucks every hour, which makes it ideally suited for high-traffic locations.
- Inspects trucks and cargo for threats with Z Backscatter imaging from three sides simultaneously, highlighting organic threats and contraband that other systems miss, such as explosives, plastic weapons, and drugs.
- Two-sided Forwardscatter® imaging and optional top-down transmission imaging allow for a more thorough inspection
- Extremely high throughput at 80 trucks per hour
Features
- Organic discrimination with multi-view Z Backscatter technology
- Dual-sided Forwardscatter imaging displays dense regions of images
- Scan Speed: Drive through imaging at speed of approximately 4kph
- Throughput: 80 trucks per hour
- Ideal for high-traffic locations: Compact design and profile that works well with space constraints and a high-throughput requirement
- ASEInspection software with multiple image analysis tools
Options
- Configurable with up to three imaging modules: top view assists with manifest verification; left and right sides extend field of view, to include tires and gas tanks that are typically cut-off in transmission images.
- Top-down transmission imaging
- Integrated license plate reader
- Integrated under vehicle inspection system
- Radiation portal monitor
- ASE Connect networking
- Available in Gantry configuration called Z Gantry™ system, a multi-view Z Portal system on rails.
Safety
AS&E's Z Portal system uses innovative Z Backscatter technology, which ensures that the system's low radiation dose is safe for operators, drivers, and the environment. In fact, one scan is equivalent to flying one minute at altitude on an airplane. The Z Portal system meets ANSI N43.17 Radiation Safety for Personnel Security Screening Systems Using X-Ray, which is the standard that the Center for Devices and Radiological Health (CDRH) references for systems such as Z Portal.
The Z Portal system's low radiation dosage is safe for operators, drivers, and the environment and falls well within standards set by The International Council on Radiation Protection (ICRP), National Council on Radiation Protection (NCRP) and the Nuclear Regulatory Commission (NRC). The dose from the Z Portal system is less than 0.05 microSievert per scan (5 microRem per scan).
It is important to keep in mind that all of us are exposed to ionizing radiation — from sources such as the sun's rays — every single day of our lives. To put this into perspective, 0.05 microSievert is equivalent to:
- The radiation a person receives from flying in an airplane for about one minute at 30,000 feet (due to the increased exposure from cosmic rays).
- One percent (1%) of the radiation dose received by the average person on any day of the year.
The Z Portal system is equipped with numerous safety mechanisms. It is fully interlocked for X-ray safety; any malfunction that could cause an unexpected increase in exposure to the scanned vehicle is interlocked to prevent X-ray generation. The speed of vehicles driving through the Z Portal system is electronically monitored and X-rays are immediately shut off if the speed falls below the required threshold. The Z Portal system also incorporates redundant safety controls, such as emergency shutoff pushbuttons, at several locations on the systems.
Additionally, the personnel assigned to operate the Z Portal systems are specifically trained for safe X-ray system operations.
