Stories are reported about patients receiving one-time excess doses of radiation from routine scans. While imaging tests can save lives, they also expose patients to varying levels of radiation. X-rays and mammograms deliver relatively low doses, while a CT scan is much higher. Other tests, such as a colonoscopy, ultrasound or a MRI, deliver no measurable levels of radiation.
You should be aware of the effects of over-exposure to radiation. Ask if the tests expose you to radiation and find out if there is a non-radiologic alternative to the test that is ordered. Make sure that your children receive the lowest dose of radiation possible.
Reducing your over-exposure to radiation tests will reduce your risk of cancer and possibly, keep you healthy.
