Abstract
Reference x-radiations are of practical importance at the standard dosimetry laboratories. The specifications and the operational conditions required to produce reference x-radiations are described in the relevant standards, provided by the International Standards Organization (ISO) and the International Atomic Energy Agency (IAEA). In the present work, an x-ray generator, Philips RT250, has been used to produce medium energy reference filtered x-radiations. Attempts have been made to make the characteristics of the produced x-rays as close as possible to those of the standard beams.
