On the Use of a Recombination Chamber for Radiation Measurements in CERN-EU High Energy Reference Fields

Abstract

Ambient dose equivalent was determined in high energy reference radiation fields at CERN (CERF facility) using a recombination chamber and recombination methods developed in IAE. The chamber was also used for measuring the low LET background radiation which locally accompanies the fields at CERF. The measurements included determination of the absorbed dose and recombination index of radiation quality at different beam intensities. It was shown that the background might considerably influence the measurements of the absorbed dose, however, its influence on the ambient dose equivalent remains important only at low beam intensities.
