BeO(Na) TLD on the market, UD-170 L, gives thermoluminescence response equivalent to irradiation with 3.2 +/- 0.5 cGy of 60Co gamma-rays after irradiation with 10(10) thermal neutrons per cm2. Because of this neutron sensitivity, UD-170 L is not suitable for measurement of gamma-rays in gamma-neutron mixed radiation from a nuclear reactor of Kinki University when we use it for radiobiological research. To reduce this troublesome sensitivity, we replaced the glass capillary used for UD-170 L with a quartz capillary. Quartz tube encapsulated BeO(Na) showed a markedly reduced response to thermal neutrons.
市场上的BeO(Na)热释光剂量计UD - 170 L，在每平方厘米受到10(10)个热中子辐照后，其热释光响应相当于受到3.2±0.5 cGy的60Coγ射线辐照。由于这种对中子的敏感性，当我们将UD - 170 L用于放射生物学研究时，它不适合测量来自近畿大学核反应堆的γ - 中子混合辐射中的γ射线。为了降低这种麻烦的敏感性，我们用石英毛细管替换了用于UD - 170 L的玻璃毛细管。封装BeO(Na)的石英管对热中子的响应明显降低。
