The content rate of scattered radiation is affected by tube voltage, object thickness, size of radiation field and with or without grid. We tried to formalize the relationship between the content rate and them. As changed the tube voltage, object thickness, radiation field and grid ratio, radiography varies in its film density, then we calculated the content rate of scattered radiation, and led two approximate equations by the method of multiple regression analysis. One of the equations was computed by using real value X of explaining variables, another by using root value √<X> except the explaining variable of tube voltage. As a result, the latter had better accuracy. Appling this approximate equation, when each explaining variable is within the boundary area, error is not over 10 percent, almost errors within 5 percent.
