The ICRU proposed new operational quantities, which are defined in close relation to effective dose and absorbed dose. Most of the current personal dosemeters were designed to measure personal dose equivalents. Because of differences between the new and old quantities, the existing dosemeters may not be ideal for measurements of the new quantities, personal dose, Hp, and absorbed dose in local skin, Dp local skin. For photon radiation sources, we investigated relative responses of the current personal dosemeters with respect to the measurement of the new quantities. Introduction of the new quantities into practice will require some changes in practical radiation protection. A recalibration of the current dosemeters will be essential for Hp measurements in higher photon energy region (>50 keV). For lower photon energies, a redesign of specific evaluation algorithms will be necessary. For purposes of Dp local skin measurements the dosemeters do not require any fundamental changes.
ICRU 提出了新的操作量，这些操作量与有效剂量和吸收剂量密切相关。目前大多数个人剂量计都是为测量个人剂量当量而设计的。由于新旧量之间的差异，现有的剂量计可能并不理想，无法用于测量新量、个人剂量、Hp 和局部皮肤吸收剂量 Dp 局部皮肤。对于光子辐射源，我们研究了当前个人剂量计相对于新量测量的相对响应。将新量引入实践将需要对实际辐射防护进行一些更改。对于 Hp 在更高光子能量区域（>50keV）的测量，当前剂量计的重新校准是必不可少的。对于较低的光子能量，需要重新设计特定的评估算法。对于 Dp 局部皮肤测量，剂量计不需要任何根本性的改变。
