注量率  单位时间内通过单位面积的粒子数。严格的定义是在单位时间内进入以空间一给定点为中心的小球体的粒子数除以该球体的最大截面积所得的商,用φ表示。它的国际单位制单位是米-2·秒-1,习用厘米-2·秒-1。此物理量曾称通量或通量密度。注量率是表征辐射场的物理量,如一个点状中子源每秒发射的中子数为N,向四周均匀发射,则离源1米处的中子注量率φ=N/4π米-1·秒-1。注量率在反应堆物理和工程中常用,由此导出注量的概念,后者的原意是注量率的时间积分值。如果对研究的辐射场给出速度v或能量E的注量率分布函数φv或φE,则注量率。如果对研究的辐射场给出粒子数密度n或速度为v的粒子数密度nv和粒子的平均速度堸,则φv=nv·v,φ=n·堸。
