What Is Radiation Detector?

Radioactivity is everywhere around us and also under the ground. But, we just cannot sense the presence of radioactivity. So, here is when a radiation detector steps in! What is a radiation detector? It is industrial equipment that’s designed to identify and measure the subatomic particles emitted by radioactive materials in our surroundings. This device simply counts the radioactive particles and displays an average for you to make a decision accordingly.

It is significantly different from a Geiger counter. A Geiger counter cannot identify the original source of radiation or the type and amount of energy. However, on the other side, the best radiation detectors can localize the origin whether it is from a nuclear weapon, a radiological dispersal device, or through improvised nuclear devices. Plus, a Geiger counter helps detect low-level radiation like the ones present in your water, foods, nearby puddles, in the air, or your entire house.

Types of Radiation Detectors:



A radiation detector is equipment responsible for the measurement of alpha, beta, and gamma rays present in our environment. Basically, the ionization of these rays is measured with the matter that creates positively charged ions and electrons. There are detectors that can identify low levels as well as high-intensity radiations and there are certain types of radiation detectors to identify different types of particles.

Three Types of Radiation Detectors

1. Geiger Counter

This one is the most commonly used radiation detector. It works with a metallic wire that is in between a gas-filled tube chamber used at a higher voltage to collect the ionization generated due to incidental radiations. It can easily detect alpha and beta radiations. However, the gamma rays are a bit difficult to distinguish. And these are also popularly called gas-filled detectors.

2. Gaseous Ionization Detectors

Gas ionization detectors are used to detect both artificial and natural radioactive substances present in the environment. These are used in particle physics that helps identify the ionizing particles along with being used in radiation protection applications.

3. Scintillators

This device basically exhibits scintillation that’s one property of luminescence. They are coupled with an electronic light sensor like the photodiode, photomultiplier tube (PMT), or silicon photomultiplier to convert light into an electric pulse. This action is performed with the help of vacuum tubes.

Things to Consider Before Buying Best Radiation Detectors: Best Buying Guide



Since radiations are invisible and not anyone can taste or smell the same, dependency on equipment like radiation detectors increases. These indicate the presence of radiation in our environment. And radiation is essentially the high-intensity energy traveling in the form of particles that can affect human health upon prolonged exposure.

The rays coming out from microwaves, television, or X-ray machines are equally harmful when compared to cosmic particles. Radioactivity is a pretty spontaneous phenomenon wherein some unstable atoms of any element radiate energy in the form of waves. These collectively are called ionizing radiations whose intensity varies depending upon the loss of the nucleus.

So, now that you understand the process of how radiations develop and it is obvious that these can even hamper the genes of the generations to come, you must definitely go for buying the best radiation detector. However, here are a few things you need to consider before buying the best radiation detector for home use. This is a guide that’ll help you invest in the best portable radiation detector.

1. Method of Detection

The detection method can either be a standard Geiger counter gas tube identification or it can be a pancake tube. The tube type must be noted as that’ll decide what radiation particles will be collected. In the case of a Geiger, it will collect the alpha and beta particles however when you would like to measure the high-intensity gamma rays, the pancake tube does the job. So, the reliability of the detection method is a must to ensure.

2. Usage

Pay attention to your specific usage as it is important for you to know your requirements and only then make a purchase. Ask yourself why you need this equipment – Are you a professional or just a hobbyist or maybe need a radiation detector for informational purposes?

Is Radioactivity Dangerous?

The radiation is silent! It can be anywhere. And it can easily contaminate your environment resulting in dangerous health conditions. Basically, radioactivity is potentially dangerous stuff that can even cause mutilation. It happens when an unstable particle falls apart and further sends out smaller particles or rays. These are strong enough to cause human and animal cell degeneration upon direct encounters. And this way, the cells can even die or badly mutate. These particles are in the air and inside the earth. In fact, even the sun shoots at us such potentially harmful particles, however, these are too less to affect our overall well-being even in the longer run.

What Is Radiation Detector Used For?

The best radiation detectors for sale on Amazon are the equipment that is used for identifying high-energy particles like the ones produced by cosmic radiation or nuclear delay/ reactions. The most common instruments are portable radiation detectors or the ones that are handheld. But, what exactly is a radiation detector used for?

This device measures alpha, beta, and gamma radiations that are capable of damaging both humans as well as animal health. The instrument can also be used to test your food, the water, and other areas that have a risk of being contaminated.

How does Radiation Detector Works?

As opposed to how they may look, the working of a radiation detector is pretty simple. There isn’t anything too fancy or complicated. These are just small handheld kinds of equipment to help you detect the radiation particles in your environment and in fact in your food and water.

Working: There’s a cylindrical tube that acts as the sensor to measure the number of particles in your environment. This tube is again filled with a low-pressure gas that’s sealed with ceramic on one side to become conductive in a flash when a radiation particle passes through it. In the center of this tube is a tungsten wire connected to the high positive voltage that develops an electric field between the outside tube and the insides.

This electric flash is thereafter measured with audible clicks. And when more particles pass, there’s an even louder clicking produced inside the device.

The reading then generated is much higher because of the great amount of electricity generated inside the tube. And the inert gas present inside can either be neon, helium, or argon. This equipment is essentially designed to detect ionizing radiations – Alpha, beta, and gamma. The inside gas is sufficient to identify the alpha and beta rays. But, it’s difficult for gamma rays to get easily detected with low-intensity equipment as the gamma rays are high-intensity rays!

Is A Radiation Detector the Same As Geiger Counter?

Radiation detectors are often confused with Geiger counters whereas there’s actually a bit of difference between the two. There is a fine line so for your information; the sound of radioactivity was able to be heard due to the efforts of an ingenious German physicist, Hans Geiger.

Radiations aren’t visible at all and can also not be felt or smelled. You can only see its impact after prolonged exposure. So, the detection of these radiations is absolutely important for one too not to be critically affected. But, the source of radiation or the type and amount of energy, etc cannot be determined by a Geiger counter which every best radiation detector can.

Frequently Asked Questions for Best Radiation Detectors: FAQs

Before you hop on to buying the best radiation detector for home usage, clear all your doubts.

Q1. Who Is A Radiation Detector For?

This instrument is for easy detection of the radiation present in our environment, all in the name of our family’s safety. Radiation risks are dangerous – we cannot feel the rays, see them, smell, or even taste them. So, a radiation detector is for someone who would want to identify the amount of high-energy ionized particles in their environment.

Q2. What’s The Difference Between Alpha, Beta, and Gamma Radiation?

Radioactivity or radiations are atoms in an unstable state which undergo nuclear processes to become more stable and there’s an energy emission from the nucleus. The radiations then emitted are alpha, beta, and gamma.

Alpha particles are electrically charged particles that are at least penetrating and are of a shorter range however pretty damaging when ingested or inhaled.

Beta particles are also electrically charged but faster to penetrate and also hazardous. Prolonged exposure can cause skin burns or damage your eyes.

Gamma particles are an even more intense form of electromagnetic radiation. These are the most dangerous ones and aren’t easily detectable.

Q3. Are our Everyday Things Radioactive?

Some amount of radioactive material is definitely present in the things around us. Smoke detectors, television, microwave, cigarettes, ceramic dishes, cat litter, fluorescent lights, and irradiated gemstones are some of those materials.

Q4. How Can I Detect Radiation In My House?

To detect the radiation in your house, go for a portable radiation detector like a Geiger counter. This gas-filled device is a high-voltage electrical device that comes in contact with the radioactive particles to accumulate them and provide the exact measurements. It helps you identify the alpha, beta, and gamma waves to help you stay safe.
