Description

The inventive transport portal radiation monitor relates to the field of environmental protection, and more specifically to the field of registration of radioactive radiation, moreover, it can be most effectively used to register gamma radiation and neutron particle flux when moving through it various wheeled or tracked vehicles with radioactive and / or nuclear materials.

Known portal radiation monitor [1], designed to control the presence of gamma and neutron emitting radioactive and nuclear materials in humans, as well as in various small vehicles, including a two-post portal, an electronic signal processing system, scintillation detectors, spectrometric amplifiers, object detection sensors and light and sound signaling unit, and the electronic signal processing system consists of an analog-to-digital converter, a personal system block wow computer and display.

The disadvantages of the known portal radiation monitor are:

a) the impossibility of determining the specific activity of a moving object (person) or cargo transported by a vehicle due to the lack of a weight sensor in the monitor;

b) the inability to use the known monitor to control the movement of large vehicles due to the fact that the use of a monitor to control the presence of gamma and neutron emitting radioactive and nuclear materials in humans is the reason for the comparability of the overall dimensions of the monitor with the average dimensions of a person.

A radiation monitoring device is known for detecting radiation sources and radioactive contaminants (including gamma and neutron radiation sources) in a cargo of vehicles [2], including two detectors, an alarm unit, a presence sensor and a programmable electronic unit with a microprocessor.

The disadvantages of the known radiation monitoring device are:

a) the inability to determine the specific activity of the cargo transported by the vehicle due to the lack of a weight sensor in the radiation monitoring device;

b) the impossibility of preventing deliberate unauthorized passage of a vehicle through a radiation monitoring device due to the absence of a blocking of an unauthorized passage of a node in its composition;

c) a reduced probability of detecting intentionally hidden radioactive materials on the body or inside the vehicle body.

The closest in technical essence to the claimed object is a transport portal radiation monitor [3], designed to control the presence of gamma and neutron emitting radioactive and nuclear materials in various vehicles, including two side racks with detectors, an electronics unit with a microprocessor, a remote control unit with a unit display (nine LEDs) and an audible alarm unit, the electronics unit with a microprocessor connected to the detectors, a remote control and a display unit.

The disadvantages of the known transport portal radiation monitor are:

a) the impossibility of determining the specific activity of the cargo transported by the vehicle due to the lack of a weight sensor in the transport portal radiation monitor;

b) the impossibility of preventing deliberate unauthorized passage of a vehicle through a transport portal radiation monitor, due to the lack of occupancy sensors and an unauthorized device blocking it;

c) reduced probability of detecting radioactive materials deliberately hidden on the body or inside the vehicle body due to the presence of only two side racks with detectors.

The advantages of the inventive transport portal radiation monitor are the ability to determine the specific activity of the cargo transported by the vehicle, preventing unintentional unauthorized passage of the vehicle through the transport portal radiation monitor, as well as increasing the likelihood of detecting radioactive materials deliberately hidden on the body or inside the vehicle body.

These advantages are achieved due to the fact that the inventive transport portal radiation monitor includes a rectangular weight sensor located along the sides of the rectangular weight sensor, two side and four corner posts with detectors, as well as presence sensors located on the corner posts, an electronics unit with a microprocessor, a remote control with a display unit, an audible alarm unit and road blockers located at the inlet and outlet of a rectangular weight sensor, the electronics unit with a microprocessor connected to a rectangular weight sensor, detectors, presence sensors, road blockers, an audible alarm unit and a display unit.

Distinctive features of the proposed transport portal radiation monitor is that

- it further comprises a rectangular weight sensor;

- it additionally contains four corner posts with detectors;

- it additionally contains presence sensors, one on each of the four corner posts;

- it additionally contains road blockers installed at the entrance and exit of the rectangular weight sensor;

- an electronics unit with a microprocessor is connected to a rectangular weight sensor, presence sensors and road blockers.

The inventive transport portal radiation monitor is illustrated by the drawings shown in figures 1 and 2.

Figure 1 presents a top view of the transport portal radiation monitor.

Figure 2 presents a rear view of the transport portal radiation monitor.

The inventive transport portal radiation monitor consists of a rectangular weight sensor 1, racks 2, 2a, 2b, 2v, 2g, 2d, detectors 3, 3a, 3b, 3v, 3g, 3d, presence sensors 4, 4a, 4b, 4v, electronics with microprocessor 5, remote control 6, display unit 7, sound alarm unit 8 and road blockers 9, 9a.

The inventive transport portal radiation monitor operates as follows.

In the initial state (standby mode) of all the elements of the transport portal radiation monitor, only the presence sensors 4, 4a, 4b, 4c (which can be used infrared emitters, radio, optical or acoustic locators), the electronics unit with microprocessor 5 (which can be used as the system unit of a personal computer), a remote control 6, a display unit 7 (display) and road blockers 9, 9a.

When the vehicle 10 with gamma and / or neutron-emitting radioactive and / or nuclear materials approaches the road blocker 9, the driver of the vehicle 10 gives an audible signal. Using this signal, the operator using the remote control 6 turns off the road blocker 9 and the vehicle 10 enters a rectangular weight sensor 1.

When the vehicle 10 enters the rectangular weight sensor 1, the presence sensors 4 and 4a are triggered, the signals from which are sent to the electronics with microprocessor 5, after which the electronics with microprocessor 5 sends signals to the rectangular weight sensor 1, detectors 3, 3a, 3b , 3c, 3d, 3d and the road blocker 9. As a result, the road blocker 9, as well as a rectangular weight sensor 1 and detectors 3, 3a, 3b, 3c, 3g, 3d, from which the results of measurements of gamma and neutron radiation levels are turned on, are turned on, as well as weight tra of the imported radioactive materials begin to enter the electronics unit with microprocessor 5 and then to the display unit 7, where on the display screen a signal is displayed in a certain sequence or at the same time (depending on requirements) about the presence of vehicle 10 in the portal, the time of presence, and the schematic location ( mnemonic diagrams) of the vehicle 10 and detectors 3, 3a, 3b, 3c, 3g, 3d, as well as the measurement results.

When registering excesses of gamma radiation levels and neutron fluxes on the screen of display unit 7, the color of the detector (s) from which the corresponding signal was received is changed, graphic and digital measurement results are displayed, and a command is sent to the unit from the electronics unit with microprocessor 5 sound alarm 8, which gives a corresponding warning sound signal.

In the event that there were no excesses in gamma radiation levels and neutron fluxes, the electronics unit with microprocessor 5 turns off the road blocker 9a, which at the same time is a permission to leave vehicle 10 from the transport portal radiation monitor.

After the vehicle crosses 10 presence sensors 4b, 4c, a command is sent from them to the electronics unit with microprocessor 5, which again puts the transport portal radiation monitor into standby mode, and this transport portal radiation monitor can transmit controlled transport to one or the other parties without changing the functions of the elements present in it.

In addition, during the entire operating time of the transport portal radiation monitor, the electronics unit with microprocessor 5 adjusts the operation of the detectors 3, 3a, 3b, 3c, 3g, 3d depending on the total time of their operation, as well as on temperature, humidity and changes background levels of gamma radiation and neutron particle fluxes.

The inventive transport portal radiation monitor in comparison with the closest analogue:

a) due to the presence in its composition of a rectangular weight sensor has the ability to determine the specific activity of the cargo transported by the vehicle;

b) due to the presence of presence sensors and road blockers in its composition, it has the ability to prevent intentional unauthorized passage of a vehicle;

c) due to the presence of four additional corner columns with detectors, it is more likely to detect radioactive materials deliberately hidden on the body or inside the vehicle body.
