California Gov. Arnold Schwarzenegger has put his signature on the first state law in the United States aimed at protecting patients from excessive radiation exposure received during CT scans and radiation therapy procedures. The measure will impose strict new procedures and reporting requirements to protect patients from medical radiation overdoses, effective July 1, 2012. The bill also provides an accreditation mandate for CT scanners that will take effect on Jan. 1, 2013. The bill requires that radiation dose be recorded on the scanned image and in a patient's health records and that radiation overdoses be reported to patients, treating physicians, and the state Department of Public Health. It requires the same level of monitoring for therapeutic radiation used to treat cancer.
