Radiation Meter, what is it and how much does it cost?

November 2, 2021

radiation meter is a device used to find out the radioactivity in a physical space or an object. There are several models, some more powerful than others, that have the purpose of measuring nuclear radiation, electromagnetic radiation and the radiation of sunlight emitted from the surface of the star.

It is an instrument that has gone through a long history, firstly being a device to know the presence of radiation in plants where nuclear elements were used. And then for everyday use in homes or businesses where there could be a radiation exposure and its respective source.

Pay attention, because next we will talk about what radiation meters are and how they work . Devices that can help you know if there is any radiation exposure in a room, and even in food. Accurate and versatile, they will accompany you wherever you want to go thanks to their compact size.

What is a radiation meter?

The radiation meter, also known as a Geiger counter , is a digital or handheld device used to detect radiation charges in a physical environment or on a specific object. It is an indispensable laboratory instrument, especially in chemistry, where users are exposed to various radiation loads in tests.

What does a Geiger counter measure?

In order to understand what a radiation meter is, you must first specify what it measures. Radiation is a phenomenon of energy propagation that takes the form of electromagnetic waves or subatomic particles that are given off in a vacuum. There are different types of radiation depending on the source from which it was emitted.

For example, if the radiation comes in the form of electromagnetic waves it is known as electromagnetic radiation . Such is the case with ultraviolet rays. On the other hand, when energy is measured by subatomic particles, it is known as corpuscular radiation . Such is the case with neutrons.

Finally, if the energy is capable of generating ionization, it is known as ionizing radiation . Obviously these particles are very small so they cannot be seen with the eyes, so a meter or a counter device is needed to know the amount that is released in the air.

What does a radiation meter read?

Knowing what radiation is, it is time to know its reading. This is represented by microsievert / hour or µSv / h . The normal amount depends on some essential characteristics, but in general it should be somewhere between 0.03 and 0.3 µSv / h.

What does a radiation meter look like?

A radiation meter is a device that has changed over time, going from being a large instrument that had to be carried as a backpack, to just being a small remote similar to a television control.

The first version of the radiation meter consists of a tube with a metallic wire . It has an isolated and gas-filled space, with a 1,000 volt wire with respect to the tube.

The way it works is this: when an electro passes through the tube, electrons are released from gas atoms that fill the entire tube. Due to the positive voltage of the central wire, they are attracted towards it and by doing this they gain energy by colliding with the atoms and releasing more electrons.

Now they are simple handheld devices, compact and that allow us to know the radiation emitted from an object or space. They calculate the levels and even indicate the source from which the strongest emission of radiation is coming. Being more precise.

How is a Geiger Counter different from a digital radiation meter?

A normal digital radiation meter with a display may be mistaken for a Geiger counter. When in fact there are some differences. Here we will mention what they are:

  • Geiger counters indicate whether there is radiation exposure in a particular area, but unlike current digital meters, they do not indicate how much radiation is, nor what type of radiation it is. So it is only listed as an informational tool.
  • Professional and modern meters are used on people, giving a data of the radiation emerged in a matter of seconds. Both inside the person, and around. On the other hand, a geige meter does not meet any of these conditions mentioned.

Types of radiation meters

Basic meters

It is a compact, lightweight personal detector used to determine the direction or location of a radiation source. It is characterized by being a precise device that even discovers the unknown source from which the radiation is emitted.

Gamma radiation meter

This device is used when the range of energy emitted by radiation has been extended to hot areas. The device works with isotopes and is a means to control large radiation emissions.

What radiation counter to buy?

There are various types of radiation meters on the market . Some better than others. Here we will mention which are the best and cheapest.

PCE-EMF 823

It is a single axis electromagnetic radiation meter to be able to measure electromagnetic fields. It has a portable hand shaft and is one of the most accurate on the market.

It is mainly used to assess the risks associated with exposure to power lines. As could be the case of the industrial devices of a commercial establishment or business.

iParaAiluRy

It is a high quality digital meter that is used to measure electromagnetic radiation. It is also a great EMF sensor and indicator that can be tested for radioactive energy emissions around a physical space or person.

It is a new, feasible, easy-to-use and low-cost product that has two canisters: one for power and the other for data. It also has an alarm that indicates a high energy exposure. It is ideal for small spaces such as an office, a control room, and a wiring space.

Born and raised in Brussels in an English family, I have always lived in a multicultural environment. After several work experiences in marketing and communication, I came to Smart Water Magazine, which I describe as the most exciting challenge of my career.
I am a person with great restlessness and curiosity to learn, discover what I do not know, as well as reinvent myself daily, someone who is curious about life and wants to know. I enjoy sharing knowledge.
This is my personal project but I also collaborate in other blogs, it is the case, the most important web on water currently exists in the US, if you are interested you can read my articles here.
