Sentences with phrase «ionising radiation»

"Ionising radiation" refers to a type of energy that can be harmful to living things. It has the power to remove electrons from atoms or molecules, creating charged particles called ions. This radiation can come from natural sources like the sun or from man-made sources like X-rays. Exposure to ionising radiation can have health risks, so it's important to protect yourself from it.
