Radiation Explained Put quite simply, radiation is energy traveling in the form of particles or waves — such as light and heat. The atoms of certain heavy elements like uranium and plutonium emit a type of high-powered energy called “ionizing radiation.” Ionizing radiation has enough energy to change the structure of the atoms it collides with. Typically, it causes these atoms to lose an electron, which then makes them “ions.” An atom that emits ionizing radiation is described as “radioactive.” These atoms will eventually quit being radioactive as they release their energy over time. Radiation Explained Types of radiation The different elements in nuclear waste emit one or more types of ionizing radiation — alpha, beta, and gamma. Alpha and beta radiation are in the form of low-energy particles, which cannot penetrate most materials; however, they can cause serious health effects if people were to inhale or ingest them. Gamma radiation is in the form of high-energy waves (like x-rays) and requires certain materials such as lead to absorb the wave and shield people from harmful exposure. Radiation Explained Sources of radiation Humans have been exposed to radiation since the dawn of time.
