When we hear the term “antimatter,” the first things that come to our minds are movies and science-fiction stories. But surprisingly, antimatter has been a part of scientific studies and practical applications for many years now. In this article, we will explore the current practical uses of antimatter, specifically positrons.
What is Antimatter?
Antimatter is the opposite of ordinary matter. Every subatomic particle, such as electrons, has its antiparticle, such as positrons. The basic properties of antimatter and matter are the same, but their electric charges are opposing. Thus, when they collide, they cause mutual annihilation and release energy in the form of gamma-rays.
Scientists produce antimatter either naturally, by cosmic rays colliding with atoms in space, or artificially, in particle accelerators.
Practical Uses of Antimatter
PET Scans
The most common and significant use of positrons is in medical diagnostics. PET scans use a radiotracer, a radioactive substance that emits positrons from the body’s tissues. The positrons then collide with the electrons from the body’s tissues, leading to mutual annihilation and releasing gamma-rays. These gamma-rays are detected by a PET scanner, which creates an image of the body’s internal organs.
The radiotracer most commonly used for PET scans is 18F, a radioactive isotope of Fluorine that decays into oxygen and positrons. PET scans are essential for early detection and monitoring of cancer, heart diseases, and neurological disorders.

Metallurgical Studies
Positron annihilation spectroscopy (PAS) is a technique used in material science to study the defects and microstructures of materials. The technique involves firing positrons at a metal sample, which embeds themselves into the sample and attaches to a negative ion. The positrons then collide with their electron counterpart and release energy in the form of gamma-rays, which can be detected and analyzed to determine the defective microstructures and their size.
PAS is a non-destructive technique and can help understand the structure of materials, such as metals, semiconductors, and polymers. It has applications in the manufacturing industry for developing new alloys and testing existing materials for durability and reliability.
Future Applications of Antimatter
Currently, antimatter production is a costly and challenging process due to the technology required to produce, store, and contain antimatter. However, scientists continue to study and experiment with antimatter, hoping to discover new applications and technologies that could revolutionize medicine and energy production.
One potential application of antimatter in the future is as fuel for interplanetary travel. When antimatter collides with matter, it releases energy, converting mass into energy through the famous equation E = mc^2. Thus, a small amount of antimatter could yield enormous amounts of energy, making it an ideal candidate for long-distance space travel.
Conclusion
Antimatter, particularly positrons, has several practical applications in the present for medicine and material science. While there are many challenges in the production and storage of antimatter, scientists continue to explore its potential for future technologies and applications.
