In today’s world we no longer use film. Instead, we use computer chips that are called digital sensors. Digital sensors are so sensitive that we can reduce the amount of x-rays we need to get a good picture.
One dental x-ray using digital sensors is equivalent to spending 15 minutes on an aircraft at 30,000 feet. So this means that a 3 hour flight from Trinidad to Miami will deliver the same amount of radiation to the body as taking 12 dental x-rays. Airline pilots do this every day.
