How are radiation detected?
Detecting radiation is achieved through the use of a variety of instruments. The most common type of radiation detector is a Geiger-Mueller (GM) tube, also called a Geiger counter.
How are beta rays detected?
Detection of Beta Radiation using Scintillation Counter They are widely used because they can be made inexpensively yet with good efficiency, and can measure both the intensity and the energy of incident radiation. Scintillation counters can be used to detect alpha, beta, gamma radiation.

How far can alpha radiation be detected?
Alpha particles, because they are highly ionising, are unable to penetrate very far through matter and are brought to rest by a few centimetres of air or less than a tenth of a millimetre of biological tissue (Figure 2).

What are 3 ways to detect radiation?
When talking about radiation detection instruments, there are three types of detectors that are most commonly used, depending on the specific needs of the device. These are: Gas-Filled Detectors, Scintillators, and Solid State detectors.
How are particles detected?
Physicists investigate particle interactions by placing devices known as particle detectors in a region where collisions are expected. Particles that emerge from the collision leave evidence of their passage through the detectors.
What is the penetrating power of alpha?
Penetrating power
| Radiation | Range (cm) | Ionising power |
|---|---|---|
| Alpha | 3-5 | Highly ionising |
| Beta | about 15 | Ionising |
| Gamma | much longer | Weakly ionising |
Can we detect neutrinos?
Neutrinos are tiny, subatomic particles. Billions of them pass through us every second—mostly coming from our sun. But unlike the sunlight we can easily see, neutrinos are very hard to detect. To “see” them, we have to build really big detectors and block out signals from any other particles.
