A Buyer’s Guide to Radiation Detectors

Before you start sifting through listings to find the best device to detect nuclear and radioactive environments, knowing the most important features is crucial. You want equipment that has a high reliability when you need it the most. The best device will handle every aspect of radiation detection without missing one.

Method Utilized for Detection

One of the things you want to make sure is that you understand how radiation is detected. There are several different ways that a device can detect nuclear radiation. For instance, your equipment might use a standard Geiger-Muller tube, or it might use a pancake tube that handles the same thing at the same time but that has a slightly different shape.

If your device uses a tube, it’s important to know that the tube type is relevant for what you need it for. As an example, the device with a pancake tube is going to be better at detecting gamma and beta radiation, but it will not be as reliable for alpha radiation as another one might be.

What You Will Utilize the Device For

Before you choose to purchase one of these items, you should be aware of what you want to use it for. Consider the reasons you want an item like this one, whether that be for hobbyist or professional reasons. If you want it for informational purposes, consider that while making a decision about which detector is right for you. Some items are made for people who are just curious about their surroundings, while there are also items for those who have professional needs.

Display Option for Nuclear Detection

Another one of the things to consider is the display on the item. The top options, no matter where you shop, are going to feature a bright, clear display that you can easily read. This is going to make life easier when you need to take a look at the item in low light situations. If you want to ensure you have an item that offers the best data efficiency, it should be easy to see.

Other Important Specifications

While the items above are some of the most important, that doesn’t mean they are all you should consider. Below, we’ll offer insight into other features that may work well for your needs.

  • Automatic data recording – You can look back at the data to see what has happened in the past.
  • USB connectivity – Allows you the ability to charge the device and/or put your data on a computer or other device.
  • Alpha, gamma, beta, and x-ray detection – If you want the largest number of detection options, your device should detect, x-ray, gamma, alpha, and beta rays.
  • Audible ticking alarm – This offers you an audible ticking alert if the radiation in the area is higher than it should be.
  • Front LED indicator – An LED indicator can give you information about the device and whether it is operating properly.
  • LCD module – A large screen with additional information can be helpful when using the item on a regular basis.
  • Sensors or temperature and other things – The more sensors the item offers, the more it is going to be capable of doing for you.
  • Lightweight, compact design – Those who plan to utilize the item in various situations will want it to be lightweight and easy to transport.

Of course, you should also consider whether the detector for radiation is easy to utilize, has a solid quality build, and is large enough to be useful for your needs.

Frequently Asked Questions About Radiation Detectors

Now that we’ve talked about your options for the best device to check radiation levels, you may have a few questions. This type of nuclear detector device can be utilized to measure the number of particles in the area around you that comes from radioactive equipment or items.

Below, we’ll talk about important things like whether your smartphone can detect nuclear activity and what the best device is to determine whether levels are too high.

Can a smartphone detect radiation?

It might seem crazy to believe that smartphones can be utilized as radiation detectors, but the United States government has proven this is a reality. Smartphones are created in a way where they can not only detect gamma rays but also the energy spectrum of radiation. It can calculate the radiation dose and determine where the radiation exposure is coming from.

There are also now apps for both Apple and Android devices that utilize the onboard silicon-based complementary metal-oxide-semiconductor (CMOS) to monitor radiation levels in the area around you. Readouts can be made in roentgens per hour, (R/hr), rem per hour (rem/hr), millirem per hour (mrem/hr), and milliroentgens per hour (mR/hr).

What instrument do you utilize to detect radiation?

Radiation is not something you can detect through the human sense. Instead, there are several instruments utilized to detect and measure radiation. The most common radiation detectors include:

  • Geiger counters – Geiger counters include a gas-filled tube that makes an electrical pulse when radiation interacts with the gas. The pulses result in an audible click that you can hear and often feature a readout in mR/Hr, rem/hr, or R/hr.
  • MicroR meter – This is a solid crystal of sodium iodide that pulses light when interacting with radiation. The light is turned into an electrical signal, which creates a reading on an instrument meter. These radiation detectors can be utilized as a handheld or large stationary option for radiation detection.
  • Portable multichannel analyzer – It uses a crystal as above but with a small multichannel analyzer electronics package and is becoming more affordable. These radiation detectors are an option for automatically identifying and displaying the radioactive items present.

Some of the other radiation detectors available include neutral REM meters, ionization chambers, and radon detectors.

What is the difference between a Geiger counter and a radiation detector?

A Geiger counter an item among many that can offer radiation safety through the detection of radiation. It offers information on whether there is radiation nearby but does not tell you where the radiation is coming from or its dose rate. Personal radiation detectors are worn on people and can show you where the radiation is coming from, which makes it easier to determine a nuclear threat and handle the situation.

Essentially, radiation detectors do what the counter does but also has other features. Many include a larger number of detection options for gamma, alpha, beta, and x-ray. This kind of device may also come with things like extension poles or rechargeable batteries. They often monitor dose rate, nuclear peak values, and stay. These are safe for people to utilize even in explosive environments that require special equipment.

How can I check my radiation level?

Having access to radiation detectors makes the process of determining how much radiation is in your home a cinch. It reveals the exact amount of radiation nearby and can create a beep or other noise if the number is too high. Depending on the radiation detectors you utilize, you also may be capable of determining important information, including where the radiation is coming from. The best dosimeter device can also provide information about hidden and unidentifiable sources of nuclear radiation.

If the levels are low or standard, there is very little to worry about. If you find that the numbers are too high, a device like a reliable ventilation system can help prevent the problem. Protective material or shielding can also be useful when your radiation detectors note that the level of radiation is high.

Wrapping Up

When you need the best radiation detector possible, you want to be sure you search for items that help in your specific situation. While nobody wants to be in a situation with radiation, the right device can keep you safe if you are. The best radiation detection device will also show you where radiation is coming from and what level of radiation it is.

Try one of the devices we showcase above to get the best results. If the perfect device isn’t listed, you now know how to find the item you want. Good luck out there!
