查询词典 dosimeter

In radiation dosimetry there are numerous limitations associated with the measurement of isodose curves and depth-dose distributions in high gradient regions of beams by using conventional measuring systems, such as ionization chambers, diode dosimeter, thermoluminescent detectors, and radiographic films.

在辐射剂量学中，利用传统的剂量计例如游离腔、二极体侦检器、热发光剂量计、感光胶片…等，来量测等剂量曲线或是深度剂量分布都有其适用的范围及其限制。

The energy spectra of hot electrons have been measured using the magnetic spectrometers, fitted with the LiF thermoluminescent dosimeter which were calibrated using Cs~(137)γ-ray sources, in the interaction of a 130 mJ, 60 fs, 800 nm, 1∶10~(-6), 7.0×10~(17) W·cm~(-2) P-polarized laser incidence on Cu foil target at an angle of 45° with respect to the target normal without any prepulse.

在激光能量130mJ，脉宽60fs，波长800nm，对比度1∶10-6，激光与靶法线成45°夹角， P偏振，靶面激光峰值功率密度约为7.0×1017W·cm-2，无预脉冲的条件下，采用电子谱仪与经γ标准源标定的LiF热释光探测器相配合，测量了飞秒激光薄膜靶相互作用中产生的超热电子能谱。

The accumulated self-exciting dose for Na-24 is only 1.12 mGy during its average life-time for irradiation of total thermal neutron fluence of 3.6E12 nth/cm^2. Conclusions: Because of the self-exciting dose reduced from neutron activation can be neglected for gamma dose measurement in neutron and gamma mixed field, and the threshold of linear response is 2 Gy, the FWT-70-40 dosimeter not only can be used for high dose rate Co-60 irradiation field and the high energy electron beam for medical purpose, but also can be used for gamma dose measurement in an epithermal neutron beam for boron neutron capture therapy.

型号FWT-70-4OM）剂量计於BNCT高中子通量与剂量的中子、加马混合辐射场所产生的自激剂量，对加马剂量度量干扰可忽略，且对加马的最低剂量限值为2Gy，因此除可应用於钴60加马高剂量辐射场与放射治疗用高能量、高剂量电子射束的剂量度量外，亦可应用於BNCT照射治疗用高能量、高剂量的中子、加马混合辐射场的加马剂量度量。

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。
