Patient Resources

Patients often have questions about the radiation dose they receive from medical imaging exams and procedures. Radiologic technologists can direct their patients to a free, online resource designed to answer many of those questions.

X-ray Risk.com is an independent educational website that provides information on medical radiation. The American Society of Radiologic Technologists is a sponsor of the site. One of the site's main features is a calculator that allows users to estimate radiation dose from CT scans, x-ray exams and other medical imaging procedures.

Site visitors can log in and create a web-based personal record to track their medical imaging history and generate information about cancer risk. There is a frequently asked questions section on the site that addresses topics such as background radiation, airport scanners and radiation protection.
