What Are They?

Radiation detectors are specialized pieces of equipment that are used for measuring electromagnetic, nuclear, and light radiation.

A nuclear radiation detector identifies nuclear radiation by measuring the release of ionizing radiation from beta, gamma, and alpha particles. They are also called Geiger counters.

Nuclear radiation detectors have two primary elements:

• The Geiger tube
• Processing electronics

How Do They Work?

Scintillation radiation detector

A specialized material like sodium-iodide is used to detect radiation. Once radiation comes into contact with the material it starts glowing or scintillating.

The light that is emitted can then be seen through the clear glass when it communicates with the photomultiplier tube.

The tube tip is made from a photocathode which generates electrons when the light hits its surface. The electrons are drawn to a collection of plates by applying positive high voltage.

Dynodes

Once electrons reach the first plate (dynode), multiple electrons are generated for every initial electron that reaches its surface.

Once these groups of electrons are drawn to the next dynode, the sequence repeats itself until it reaches the very last dynode.

At this stage all electrons are gathered by the anode on the tube, creating an electrical pulse. This pulse is perceived and shown by the radiation detector.

Gas filled radiation detector

Geiger tubes are crammed with low-pressure gas like neon, helium, or argon. When radioactive radiation happens, the inactive gas gets ionized.

The anode found inside the Geiger tube measures the number of ionized elements numerically, compared with the radioactive radiation strength.

These measurements are then shown on the LCD screen of the radiation detector.

Measuring nuclear radioactivity and classifying the values is essential. It helps you identify hazardous radiation levels present in the air, water, food, appliances, and electronics.

Types Of Detectors

There are 3 primary types of radiation detectors and they all have unique weaknesses and strengths that make them suitable for particular roles.

Gas filled detectors

Gas filled detectors are the most widely used devices. There are different types but they all work on similar principles.

Once the gas inside the detector touches radiation, the gas becomes ionized and then the subsequent electrical charge is measured by the meter.

Scintillators

The 2nd most used radiation detectors are scintillators. Scintillators emit light and when used for radiation detection, certain materials scintillate once exposed to radiation.

These are useful radiation detectors because every photon of radiation that comes into contact with scintillator matter will emit a unique flash of light.

This means that they can detect particular spectroscopic profiles for the radioactive materials that were detected.

Solid state detectors

Solid state radiation detectors work similar to ion chambers, but on a relatively smaller scale and lower voltage.

This type of detector can be incredibly useful for electronic dosimetry uses. They can resist higher amounts of radiation which makes them a good fit for areas with high radiation fields.

Features To Consider

The main features to consider when buying a radiation detector are:

Means of detection

There are two detection options, a pancake tube or a gas tube. Tube types are essential because they depict which radiation particles can be detected.

For example, pancake tubes can collect beta and alpha particles as well as gamma rays of high-intensity.

Usage

Your particular usage is vital because some models are more suited for hobbyists, while other types have more extensive features for professional use.

Display

It is recommended to have a bright display that is clear and easy to read. Most devices feature an LCD to present accurate measurements.

Additional specs

Features that you should look for when investing in radiation monitoring devices include size, compactness, user-friendliness, USB connectivity, audio alerts, and more.

It all depends on your individual requirements and what you’ll be using the device for.

Conclusion

Being exposed to hazardous radiation without even knowing it is possible since they can’t be felt, seen, or smelled.

Only after long-term exposure can you see the impact, but by then it might be too late. That’s why radiation detection is absolutely necessary, it helps you avoid being severely harmed.

Keep in mind, there is a slight difference between radiation detectors and Geiger counters. Do not confuse the two.

The source of radiation can’t be identified by a Geiger counter but it can be identified by any radiation detector.
