This article explores the use of hydrogels as a potential solution for mitigating the risks of radiation exposure during deep-space missions. It discusses the challenges posed by radiation, the advantages of using water as a shield, and the innovative properties of super-absorbent polymers (SAPs) as a more effective alternative.
Radiation exposure is a significant challenge for humans undertaking deep-space, long-duration missions. It poses a serious health risk to astronauts and can also damage equipment and operating systems. Water has emerged as a potential solution due to its ability to act as a radiation shield. The hydrogen-laden H2O molecule is relatively dense and can effectively slow down radiation particles.
Furthermore, astronauts will require substantial amounts of water for various purposes on these missions.On Earth, we benefit from a natural water shield provided by the atmosphere, augmented by the Earth's magnetic field. Radiation exposure in space originates primarily from two sources: space weather emanating from the Sun and cosmic radiation from outside the solar system, including ancient and exotic sources like supernovae explosions. The 11-year solar cycle intensifies solar activity, leading to periods of heightened radiation exposure. Astronauts have reported seeing flashes in their eyes, even with them closed, since the early days of the Space Age. This phenomenon is attributed to high-energy particles interacting with the aqueous and vitreous humors in the eye, and even the brain. While astronauts in low Earth orbit have sought shelter from solar storms in the core modules of the International Space Station, providing some protection, water-based radiation shielding presents its own challenges. Bulky water suits can restrict movement and are susceptible to leaks, a critical issue in the space environment. Super-absorbent polymers (SAPs) developed by the Chemistry and Biomaterials Group (PBM) at Ghent University offer a promising alternative. These SAPs can absorb up to 100 times their weight in liquid, making them lightweight and portable. Imagine the 'monster toys' that expand in size when water is added – that's essentially how SAPs work. Unlike traditional circulating water systems, the water within a hydrogel is not freely flowing, making it resistant to leakage even when punctured. The potential of hydrogels extends beyond radiation shielding. They are already widely used in consumer products such as soft contact lenses, biomaterials, and medical bandage gels. Their versatility and ease of processing make them attractive for various applications
