Radiation dose

Why we measure it - Every day, our bodies absorb small amounts of radiation from the environment. Children's Hospital of Wisconsin participates in the Image Gently campaign, an initiative created to increase awareness of the opportunities to lower radiation doses when imaging children. We perform many different types of imaging tests that use lower doses of radiation than what is naturally absorbed on a daily basis.


What this means - When a child needs an imaging test, we make every effort to use the lowest radiation dose possible. Nuclear Cystograms, chest X-rays and head CT scans produce less radiation than what is naturally released in the environment and absorbed by the body on a daily basis.

About the data - We have illustrated the amount of radiation in everyday life versus commonly ordered imaging exams. Millisieverts are the units used to measure the amount of radiation absorbed by the body. These are average dosages only.

How we provide the best care

  • Image GentlyYour child's safety is our number one concern. Our radiologists review all tests that are ordered to see if other tests can be used that do not use radiation. If an X-ray or CT scan is needed to show a better result, we use the lowest amount of radiation possible.
  • Children's Hospital is one of three pediatric hospitals in the country that uses the state-of-the-art EOS low-dose radiation scanner. This scanner is mainly used for children with a spine problem called scoliosis.

Team approach

  • Our experienced technologists are comfortable working with children. They will educate you and your child about what to expect during an imaging scan. They use special techniques to help position your child to get the best image. Lead shielding is used, when needed, to protect the child's body as much as possible from radiation.
  • Our Child Life specialists help calm and relax your child before, during and after a scan. They provide many distraction and relaxation techniques, such as breathing exercises, music, movies, and video games, to help your child cope during a test.
  • We have physicists on staff to ensure the correct dose of radiation is given to each patient and to make sure the medical equipment that uses radiation is working safely.
