The risks with #SpaceRadiation ☢️ are assigned the highest priority among all risks associated with #SpaceTravel. Active shielding 🛡️ methods, which use #electromagnetic fields to deflect charged particles, can make #DeepSpace 🌌 travel safer and more feasible. Placing the passive shielding before the active shielding is more effective than placing the identical active shielding before the passive shielding of the same thickness https://www.sciencedirect.com/science/article/pii/S2214552423000391

Increasing evidence shows that the lack of gravity and exposure to the sun’s radiation ☢️ in space can accelerate aging in human stem cells and promote their transformation into cancer cells.

📆 1989 Had you been flying around the #Moon 🌙 at that time, you would have absorbed well over 6 Sieverts of radiation ☢️ - a dose that would most likely kill 💀 you within a month or so.

📆 2024 “It wasn’t possible 10 years ago. Using grid-like, porous structures we not only brought the weight down, but we also brought the needed power down from megawatts to 100 watts. Such shields 🛡️ are not #ScienceFiction anymore” https://arstechnica.com/science/2024/03/shields-up-new-ideas-might-make-active-shielding-viable

Traditional shielding strategies aim to reduce #astronaut radiation ☢️ exposure by increasing vehicle mass, but this is ineffective for the extremely penetrating #galactic cosmic rays. #Astronauts will face radiation hazards resulting from solar ☀️ activity that can create solar energetic particles. Active shielding 🛡️ approaches are likely a required component of any realistic solution (#electrostatic shielding) https://www.sciencedirect.com/science/article/abs/pii/S0969806X22000494

#Radiation ☢️ shielding is a mandatory element in the design of an integrated solution to mitigate the effects of radiation during long #DeepSpace voyages for human exploration. #Kevlar has radiation shielding 🛡️ performances comparable to Polyethylene, reaching a dose rate reduction of 32 ± 2% and a dose equivalent rate reduction of 55 ± 4% (for a shield of 10 g/cm2). https://www.nature.com/articles/s41598-017-01707-2
