Abstract
The atmospheric neutrino flavour ratio measured using a 1.52 kton-year exposure of Soudan 2 is found to be 0.72 +/- 0.19(-0.07)(+0.05) relat ive to the expected value from a Monte Carlo calculation. The possible background of interactions of neutrons and photons produced in muon i nteractions in the rock surrounding the detector has been investigated and is shown not to produce low values of the ratio.
