New breakthrough against radiation: Korean Scientists create revolutionary shield with nanotechnology

Korean Scientists develop new nanotechnology material capable of reducing radiation impacts in space missions, hospitals, and power plants.

The search for more efficient protection technologies in extreme environments has just gained an important advance. Korean Scientists have developed a radiation shield based on nanotechnology capable of blocking different types of harmful emissions using an ultra-thin, flexible, and extremely lightweight material. The discovery was presented in a study published in the scientific journal Advanced Materials on March 4, 2026 and is already attracting interest for its possible applications in strategic areas.

The new project stands out because it combines characteristics considered rare in shielding systems. The new material created by the researchers is thinner than a human hair, can be stretched like rubber, and still maintains high performance against radiation. According to the released results, the compound can block up to 99.999% of electromagnetic waves and approximately 72% of neutron radiation.

The technology was developed by researchers from the Korea Institute of Science and Technology (KIST), including scientist Joo Yong-ho, affiliated with the Extreme Environment Shielding Materials Research Center. For the experts involved in the study, the advance could represent a new generation of solutions for space, hospital, industrial, and technological protection.

Korean Scientists bet on nanotechnology to face the risks of radiation

Exposure to radiation continues to be one of the biggest challenges for modern technological sectors. In space missions, for example, astronauts constantly live with energetic particles capable of causing health damage and compromising sensitive electronic equipment.

Beyond space, radiation is also present in hospitals, nuclear power plants, laboratories, and advanced industrial systems. Many professionals work daily exposed to different levels of these emissions, which reinforces the need for more efficient and comfortable protection methods.

It was precisely with this scenario in mind that Korean scientists decided to create a lighter and more adaptable radiation shield. The proposal was to develop a material capable of combining high protection, flexibility, and low weight, something extremely important, especially in the aerospace industry.

The use of nanotechnology was decisive in achieving this result. According to the researchers, the created structure has a minimal thickness comparable to adhesive tape but shows advanced performance in blocking particles and electromagnetic waves.

New material combines carbon nanotubes and boron nitride

The project’s differential lies in the composition of the new material. Korean scientists used carbon nanotubes and boron nitride nanotubes to create the protection system.

Carbon nanotubes are known for their high mechanical strength and ability to conduct electricity and heat. In the new radiation shield, they help absorb and reflect electromagnetic waves that can affect electronic equipment.

Boron nitride nanotubes, on the other hand, play a fundamental role in capturing neutrons, a type of radiation considered highly harmful in extreme environments.

Among the main characteristics of the material are:

• Ultra-thin and extremely lightweight structure;
• Ability to block up to 99.999% of electromagnetic waves;
• Reduction of about 72% of neutron radiation;
• Elasticity capable of doubling the material’s size;
• 3D printing compatibility.

The combination of these properties places the project among the most promising currently in the technological shielding sector.

Space exploration appears as one of the areas most impacted by the discovery of Korean Scientists. In space travel, protection against radiation is considered an absolute priority due to the risks associated with prolonged exposure.

Space agencies, including NASA, have already released studies showing that astronauts exposed to cosmic radiation may face an increased risk of cancer, neurological problems, and cardiovascular diseases on long-duration missions.

In this context, the new radiation shield created with nanotechnology could represent a strategic alternative. As the new material has reduced weight, it can lower operational costs and improve the efficiency of space launches.

Another important point is its flexibility. The material can be molded into different shapes, facilitating applications in:

• Space suits;
• Satellites;
• Orbital stations;
• Scientific equipment;
• Sensitive electronic systems.

According to Joo Yong-ho and the other Korean scientists involved in the research, the objective is to create solutions capable of protecting both humans and technological devices in extreme environments.

Honeycomb structure enhances nanotechnology efficiency

Tests conducted by the researchers also revealed another important detail. When the new material is molded into a honeycomb-like shape, its efficiency increases by approximately 15%.

According to the Korean scientists, this structure improves the distribution of radiation over the material’s surface, increasing its capacity for absorption and energy dissipation.

The result reinforces the potential of nanotechnology applied in advanced protection systems. In addition to improving the performance of the radiation shield, the shape helps maintain the lightness and flexibility of the compound.

Another aspect that caught the researchers’ attention was its elasticity. The material can be stretched up to twice its original size without losing structural efficiency. This significantly expands the possibilities for application in industrial and space sectors.

Medicine and nuclear energy could gain more efficient protection

The applications of the discovery go far beyond space. Medicine is one of the areas that can be directly benefited by the advancement of Korean scientists.

Hospitals daily use equipment that works with different types of radiation, especially in imaging exams and oncological treatments. Healthcare professionals frequently rely on heavy garments for protection.

The new radiation shield could pave the way for lighter, more flexible, and more comfortable equipment. The use of nanotechnology could enable the development of modern medical aprons, hospital coatings, and more efficient protective barriers.

In the nuclear industry, the new material also emerges as a relevant alternative. Currently, many protection systems use lead and other heavy compounds.

With the technology developed by the Korean scientists, it would be possible to create lighter structures without compromising operational safety. This can reduce logistical costs and facilitate operations in complex industrial environments.

3D printing expands possibilities for the new material

Another point highlighted by the researchers involves the material’s compatibility with 3D printing. This characteristic can accelerate the manufacturing of customized radiation protection structures.

The combination of 3D printing and nanotechnology allows for the creation of specific components for different applications, something considered extremely important in aerospace and medical fields.

The new material can be adapted according to the needs of each project, maintaining its mechanical properties and its efficiency as a radiation shield.

Experts point out that this flexibility can accelerate future commercial and industrial applications of the discovery.

The advance by Korean Scientists can redefine technological protection

The research developed by Korean scientists shows how nanotechnology is transforming strategic sectors of modern science. The creation of an ultralight, flexible, and highly efficient radiation shield represents a significant advance for areas that depend on safety in extreme environments.

The performance presented by the new material, including the blocking of 99.999% of electromagnetic waves and about 72% of neutron radiation, places the technology among the most promising currently available.

Even though new tests and industrial validation steps are still needed, the discovery is already attracting global attention. The potential to reduce risks without significantly increasing the weight of equipment could change protection standards in hospitals, nuclear power plants, laboratories, and future space missions.

With the continuous advancement of research, Korean scientists believe that the material could play an important role in the next generation of smart shielding technologies.
