The Indian atomic energy regulatory board suggests that every X-ray examination results in radiation exposure to the person being examined, albeit small.
Recently, there have been news reports on birth certificates being issued on the basis of dental X-rays. The Indian atomic energy regulatory board (AERB) has disapproved the practice of taking dental X-ray for determination of a child's age, and has warned such practice are deviations from the terms of its license and registration. The AERB said, "As the regulator for radiation safety in the use of X-rays for medical diagnostic applications, we don't approve such routine use of dental X-ray examination solely for the purpose of age determination. Every X-ray examination results in radiation exposure to the person being examined, albeit small."
