The responses of TLD-1010, TLD-700 and TLD-600 thermoluminescence dosemeters to the radiation field inside a water tank enclosing an isotopic 241Am-Be neutron source are analysed. Separate contributions coming from thermal neutrons, neutrons with energies above thermal and gamma rays to the total response of the three types of TLD are obtained. This is accomplished by assuming that the gamma responses for materials with different 6Li enrichments are identical and that the neutron response of TLD-700 is negligible compared to TLD-100 and TLD-600. The last assumption is tested by Monte Carlo simulations of the neutron energy spectrum at the points where the TLDs are irradiated.
分析了TLD - 1010、TLD - 700和TLD - 600热释光剂量计对包围同位素241Am - Be中子源的水箱内辐射场的响应。得到了热中子、能量高于热中子的中子以及伽马射线对这三种类型TLD总响应的单独贡献。这是通过假设不同6Li富集度材料的伽马响应相同，以及与TLD - 100和TLD - 600相比，TLD - 700的中子响应可忽略不计来实现的。最后一个假设通过对TLD辐照点处中子能谱的蒙特卡罗模拟进行了检验。
