No. Ionising radiation is radiation containing enough energy to cause damage at a cellular level in the human body. We are all exposed to ionising radiation from our environment in our daily lives (from the sun, rocks, plants, building materials, etc). This is known as “background radiation”. While ionising radiation is used during some diagnostic imaging examinations, ultrasound uses high frequency sound waves to obtain an image of inside your body. Ionising radiation is not used to perform an ultrasound.
