Abstract. The radiochromic film dosimetry devices developed at FSUE “VNIIFTRI” and used at enterprises of the Russian Federation and COOMET countries for absorbed dose (AD) control are considered. The physical-technical and metrological characteristics of extended film dosimeters are described. The advantages of extended film dosimeters in comparison with single film dosimeters in measurement of high-intensity radiation absorbed dose are discussed.

Keywords: radiochromic film, extended dosimeter, ionizing radiation, absorbed dose, optical density, electron energy measuring wedge, uniformity of the conveyor system, scanning width of the accelerated electron beam.
