Vehicle Radiation Portal Monitors

Vehicle Radiation Portal Monitors, or VRPMs, are efficient monitors for inspecting shipments and trucks. These monitors help speed up the process of inspection, especially the inspection of radiological threats over checkpoints or roads. They are usually used at significant areas like airports and sea or dry ports. Their efficiency and reliability depend on the advanced technologies used for detection and inspection.

What makes Vehicle Radiation Portal Monitors distinct?

These monitors are capable of detecting and categorising all kinds of material, including radioactive material, instantaneously. They allow goods to be inspected and contribute to lower levels of congestion through the gates. Vehicle Radiation Portal Monitors also come with a unique design to meet the needs of customers and help reduce the cost of purchase.

Another unique feature of Vehicle Radiation Portal Monitors is that they can identify threats at high levels depending on radiation data. The data is securely shared through a communication network.

How do Vehicle Radiation Portal Monitors work?

These monitors are installed as portals so that vehicles should pass through them to check whether these vehicles have any contraband material on board. The monitors have two panels set in front of each other on both sides of the road to scan the vehicles.

What are the top radiation portal monitor manufacturers?

In the industry of manufacturing Radiation Portal Monitors or Vehicle Radiation Portal Monitors, we may come across numerous manufacturing brands in the market. 

On the top list of these companies, we have three premium-quality manufacturers based in different countries, such as Polimaster, a manufacturer based in Lithuania with highly qualified professionals; then we have Arktis, a Swiss manufacturer specializing in manufacturing detection integrated systems; and finally, we have Bertin, a French company that develops and produces market systems.

What do we know about radiation detectors?

A radiation detector is a tool that detects and identifies particles with high energy like global radiation, nuclear ruins, and reactions.

They are also called radiation instruments or sensors and are employed to measure the levels of radiation. 

Radiation detectors have evolved throughout history. Photographic plates were first used to reveal traces of nuclear reactions. 

This also helped discover sub-nuclear particles when utilizing cloud chambers.

With the invention of transistors, a new generation of electronic detectors has started to rise. Calorimeters were used to identify and measure the amount of energy emitted from a radiation source. 

Other uses of electronic detectors may include measuring spin, charge, and momentum.

What are the types of devices of radiation detectors?

Radiation detectors can be classified according to the type of radiation they are intended to detect or according to their basic functioning principles.


  • Scintillators: They are a significant type of radiation detector used in detecting radiation. Light-emitting is known as scintillation. For radiation detection, some materials can emit sparks or scintillate when radiation hits, which makes them act like detectors.
  • Gaseous Ionisation Detectors: Radiation detection tools that are utilised in detecting the existence of ionising particles. They use the ionising effects of radiation on a sensor made of gas. The electrons and ions produced when a particle ionises atoms or molecules of gas produce a current that may be measured.
  • A Geiger Counter is one of the most common kinds of detectors used. Ionising radiation can be measured or found using a Geiger counter. It also goes by the name Geiger-Muller counter. Beta and gamma rays along with alpha and beta particles can be detected by a Geiger counter.

What do we know about the types of radiation?

The most known types of radiation are alpha, beta, and gamma.


  • The helium atoms that move quickly are known as alpha particles or double ionised helium nuclei.
  • They are extremely energetic, measured in meV.
  • Due to their huge bulk, they hardly penetrate a few cm of air or skin at most.


  • They are electrons that move quickly.
  • Their energy varies from a few MeV to hundreds of KeV.
  • Because of their relative lightness, they have greater penetration depth.


  • They are the photon stream.
  • The typical energy range is between many keV and various meV.
  • They have a very low mass in comparison. 

What are the costs of Vehicle Radiation Portal Monitors?

Prices for Vehicle Radiation Portal Monitors vary in the market depending on the manufacturer and quality of the product. Some may cost $90000-$108000 and some may cost $29999-$199999.

Finally, Vehicle Radiation Portal Monitors are vital systems for checking and inspecting vehicles using radiation. 

They are extremely reliable and efficient at detecting materials and preventing radiological threats. It is significant to use such systems to ensure receiving a full inspection process using the most advanced equipment on the market.
