摘　　要：利用热中子活化样品,合适的照射位置是取得良好活化效果的关键。经过MCNP模拟和实验测量,给出了采用国产Am-Be中子源进行热中子活化的样品照射位置的合理范围。Appropriate irradiation position is the key reason for good activation effect of the sample which is acti- vated by thermal neutrons. Through MCNP simulation and experimental measurements, a reasonable range of the irradiation position of the sample activated by thermal neutrons for Am - Be neutron source is given.
