[en] A measurement method of neutron fluence distribution for intensive beam generators based on the fission tracks was described. The distribution at different distances along the 0 deg direction of the deuteron beam from the target was measured and the results were compared with the results of A1 activation and the theoretical calculation. The neutron fluence distribution for different angles on the plane which was 11.3 cm from the target was also measured. The neutron fluence distribution on the spherical surface was then calculated and compared with the theoretical calculation. The two agreed within the experimental error
