在测量快中子（ｎ，ｐ）反应的实验中，同样利用屏栅电离室测得聚乙烯薄膜反冲质子的能谱，并利用蒙特－卡罗方法对其进行校正，从而得到中子的绝对注量率。将其结果与２３８Ｕ测得的结果进行比较，二者在误差范围内相同，说明用此方法测量中子绝对注量率是可行的。
In the experiment of measuring the fast neutron (n, p) reaction, the energy spectrum of the recoiled proton of the polyethylene film was measured by the same method using the grid ionization chamber and corrected by the Monte Carlo method to obtain the neutron Absolute flu rate. The results are compared with the results of 238U, which are the same within the error range, which shows that it is feasible to measure neutron absolute fluence rate by this method.
