Irradiated Salt Is Weird

Does irradiated salt become radioactive? Surprisingly, no. Only neutron radiation can make materials radioactive, so this salt is safe. The irradiation gives the salt an unusual orange hue, not due to impurities but due to defects in its crystal lattice called F-centres. These defects alter the salt's color by affecting its molecular orbitals. In this video, we'll explore the fascinating properties of irradiated sodium chloride, demonstrate how its color changes back to white when heated, and discuss its potential use as a thermoluminescent dosimeter, which measures radiation exposure. Join us to learn about the intriguing science behind this altered salt!
