How can we protect ourselves from radiation exposure during space travel or living on other planets ?
Radiation exposure is a significant concern for astronauts during space travel and for future settlers on other planets. Shielding, distance, time management, and medication and supplementation are effective ways to protect against radiation. Lead, concrete, and water are good shielding materials. Distance from the source of radiation reduces exposure. Time management involves limiting the duration of exposure. Antioxidants, amifostine, and melatonin may help protect against radiation damage by reducing oxidative stress and promoting DNA repair.
