Question Video: Nuclear Radiation Emission by Objects outside Earth Science

Video Transcript

Does any nuclear radiation emitted by some objects beyond Earth reach Earth?

When we think of objects beyond Earth, that would be any object in space. Nuclear radiation is created in stars, and that includes our Sun. Just as light from the sun reaches Earth, so does nuclear radiation it gives off. Most radiation from space, called cosmic radiation, is blocked by Earth’s atmosphere. Nonetheless, some does make it through and reaches Earth’s surface. In answer to this question, then, we can say, yes, nuclear radiation emitted by some objects beyond Earth does reach Earth.
