RESUMEN
An original method for determination of the effective dose received by patient during digital scanning fluorographic examination from the results of measurement of radiation dose scattered by patient's body was suggested. This method does not require radiation detector to be exposed to working field. This method of determination of the effective dose of radiation scattered by patient's body can be used in scanning radiography.
