The possibility of using ²⁰⁹Bi as a new threshold detector to measurc high-energy neutrons was investigated for the first time. At the same time the experiment measured successfully the emitted neutron fiuence rate, energy spectrum and dose equivalent rate distributions in the heavy ion target area using a detector complex including ²⁰⁹Bi, ¹¹⁵In, ²⁷Al, ¹⁹F and ¹²C samples.
