IAEA in Basic Safety Standards (1994) presented Guidance levels of dose for typical Diagnostic radiology. Then, IAEA advises us against being over this level. Again, ICRP in ICRP Publication 60published setting "dose constraint" as upper bounds of individual exposure.<BR>However, many medical treatment facilities don't have a dosimet er in order to measure patient dose.<BR>Then, we measured X-ray output of many X-ray equipments. We statistically analyzed many data measured and could make an approximate equation in order to estimate X-ray output (air ab sorbed dose) of X-ray equipments.<BR>The X-ray output is directly proportional to V<SUP>2.232</SUP>, where V is the tube voltage. The coefficient of determination showed a high value.<BR>By revising this approximate eq uation with various revision coefficients, we made an estimated equation could estimate patient dose in Diagnostic radiology. We think that this estimated equation of patient dose can easily employ any medical treatment facilities.
