[Formation and study of the dosimetric characteristics of wide fields of fast electrons used to irradiate laboratory animals using the LUE-25 accelerator].

: A mode of formation of wide fields of fast electrons at LUE-25 accelerator is proposed to expose uniformly the extended 4 cm thick biological objects. Dosimetric characteristics of the electron beams have been studied by film and ferrous-sulfate dosimeters. The potencies and limitations of using the dosimeters as a "witness" are discussed.
