Researchers developed a aerogel for real-time detection of radioactive gases, with 96% efficiency for krypton-85 and 18% for tritium.
Researchers have created an innovative aerogel that provides real-time measurements with high sensitivity to specific radioactive gases.
The method is highly sensitive, measuring less than 100 mBq per cm³ in 100 seconds, and can detect both gases simultaneously, an improvement over previous methods. While these radionuclides do not pose a significant risk, precise measurement is essential for monitoring the correct operation of nuclear power plants and averting mishaps.
Aiming to address the shortcoming, scientists have developed a dependable and economical real-time detection technology based on gas-solid mixing.with a diameter of a few centimeters and a thickness of one centimeter, employing nanoparticles of materials that are scintillating and around five nanometers in size. With only 15 percent solids, this composite is translucent and has a very porous structure akin to a sponge.
