title: [Dosage fields of the "ANET-B" apparatus with 252Cf].
abstract: The paper is concerned with the results of the calculation of dose fields of neutron and gamma-radiation for an ANET-B unit. Experimental measurements were done in the tissue equivalent phantom by using photoluminescent and alumophosphate glasses, thermoluminescent and threshold detectors with neptunium foil. Divergences between calculated and all experimental data did not exceed 10-12%. It has been shown that the ratio of the contribution of neutron and gamma-components of 252Cf radiation for the ANET-B unit to the summary absorbed dose at an arbitrary point of a tissue equivalent phantom depends considerably on a distance between this point and the center of a source and changes from 2 (for a distance of 0.5 cm) to 1 (for a distance of 10 cm).
