照射量  X射线或 γ辐射在单位质量空气中产生的正离子或负离子的总电量。严格的定义是光子在质量为dm的空气中释放的全部电子(负的和正的)完全被空气阻止时,在空气中产生的任一种符号的离子总电量绝对值dQ被dm除所得的商,用X表示。它的国际单位制单位是库/千克(C/kg),以前习惯使用的单位是伦琴 (R),1R=2.58×10-4C/kg。1伦琴相当于在1厘米3标准状况的空气(质量为0.001293克)中产生的正、负离子电荷各为 1静电单位。    在早期辐射剂量测量中,测定空气中生成离子的电量是比较方便的。在充气电离室中使两极板保持饱和电位即可准确测量离子的电量或产生的电流。因此广泛使用射照量(当时称伦琴值)来表征辐射剂量。实际上,不同密度或组分的物质放在同一点的空气中,即使照射量相同,吸收剂量并不相同。如1伦琴相当于1千克空气吸收0.0089焦耳能量,而相当于1千克人体组织吸收0.0096焦耳能量。因此,照射量只是一种参考比较的物理量,根据照射量测算各种物质中的吸收剂量不是很简易的过程。还有一点值得注意,照射量只用于光子在空气中引起电离的情况,其他类型辐射虽然也可以在空气中引起电离,却不允许使用照射量。过去曾经用过的物理伦琴当量已经废除。
