What are x-rays - ️️radiant energy waves that are produced, charged, and emitted from a common center in the dental radiation tube. What does exposure time control? - ️️duration of the interval during which current will pass through the X-ray tube; this period may be stated as fractions of a second or impulses (60 pulses to a second). The amount of exposure that a patient actually receives is measured in milliampere seconds (mAs) What does milliampere control? - ️️mA describes the ...
