Abstract：
In this paper Indium active detector is suggested to measure the pulsed neutrons around Electron Lanic. It can be hopefully expected to have correcrt dose response of detector in the short pulsed neutron field, high resolution ability of the neutrons to γ-rays and of against electromagnetic disturbance.
This detector was used to measure the distribution of neutron flux and dose equivalent rate both inside and outside of the 300MeV Electron Linac shield. The results are compared with TLD measurement. At the end of this paper the Indium activation products by high energy photon reaction (γ, n) are estimated.
