title: [Analytical description of the dose fields from accelerated electrons].
abstract: The paper is concerned with simple expressions describing dose fields in the water phantom from the betatron B5M-25 electron beam using the Fermi-Dirae distribution function. The peculiarity of these expressions is the utilization of such parameters that reflect the main characteristics of a dose field--the depth of distribution of 50% of the isodose and projection of the zone of a dose decline along the beam axis and in its transverse cross section. The expressions proposed here could be also used for other electron accelerators.
