The photon energy response of CaSO4:Dy teflon disk dosimeters used widely in radiation dosimetry is computed using the energy absorption coefficient values for calcium, sulfur, oxygen, and carbon taken from J. H. Hubbell's tables. For fluorine, the energy absorption coefficients were obtained from the values given by F. H. Attix for CaF2 and Ca. The energy response of the radiation-monitoring disk for the range of 10 keV to 10 MeV, relative to air, is computed and plotted. The response is maximum between 20 and 30 keV and then gradually falls to a constant at 200 keV to 10 MeV. This computed response for different energies is compared with the experimental TL response of the dosimeter. The electron energy response of these TLD disks is computed using the stopping-power values for the different component elements. The electron stopping power for sulfur and calcium from 10 keV to 10 MeV is computed using the Bethe-Bloch formula. Those for oxygen and carbon are taken from the tables given by M. J. Berger and S. M. Seltzer. For fluorine, the values are computed from those for Li and LiF given in the same tables. This calculated response is compared with the experimental beta response of the TL dosimeter.
镝聚四氟乙烯盘式剂量计的光子能量响应，是利用取自J. H. 哈贝尔表格中的钙、硫、氧和碳的能量吸收系数值来计算的。对于氟，能量吸收系数是根据F. H. 阿蒂克斯给出的CaF₂和Ca的值获得的。计算并绘制了辐射监测盘在10 keV至10 MeV能量范围内相对于空气的能量响应。响应在20至30 keV之间最大，然后在200 keV至10 MeV逐渐降至恒定值。将不同能量下的计算响应与剂量计的实验热释光响应进行比较。使用不同组成元素的阻止本领值计算这些热释光剂量盘的电子能量响应。利用贝特-布洛赫公式计算硫和钙在10 keV至10 MeV的电子阻止本领。氧和碳的阻止本领取自M. J. 伯杰和S. M. 塞尔策给出的表格。对于氟，其值是根据同一表格中锂和氟化锂的值计算得出的。将该计算响应与热释光剂量计的实验β响应进行比较。
