The system operation modes are preset by the manufacturer during the installation and are not to be changed by the operator. The following design features of the system make it possible to minimize the personnel and the inspected people radiation doses:
- X-ray generator enclosed with the X-ray protection housing
- Slit diaphragms system making it possible to obtain a narrow fan-shaped beam
- X-ray protection shutter cutting off the X-ray radiation from the generator
- Inbuilt X-ray radiation filter
- Highly sensitive digital X-ray radiation converter
- Inbuilt dosimeter purposed to monitor the dose rates people are exposed to under any mode of the X-ray generator operation
- Emergency stop switch on the portal with the fixed position of the red mushroom shaped button cuts off the X-ray radiation from the generator with the X-ray protection shutter and stops the platform;
- Red signal lights (on the portal) indicate X-rays generation and platform movement
The X-ray protection shutter cuts off the X-ray radiation from the generator in case of deviations from the system mechanisms and electronic devices operation parameters and conditions set by the manufacturer as well as in case of malfunctions. In case of a failure of the X-ray protection shutter the high voltage is not supplied to the X-ray tube. The software tests the system upon its switching on and in the process of scanning. Detected faults messages are displayed on the operator monitor. The driver’s compartment is protected with the X-ray shield installed between the driver’s compartment and the screening area. Combined shields made of transparent X-ray protective plastic and lead-plated panels are installed near the portal of the whole-body security screening system to protect the operator compartment. The transparent plastic panels can be covered with special film making it impossible to see the operator compartment from the screening area.
