The microcolony assay technique has been used to test the validty of summing equivalent doses per fraction of 14 MeV neutrons and gamma rays for mouse intestinal damage. For a 4-daily fraction schedule, in which the first one or two fractions are given as neutrons and the remainder as gamma rays, combined dose fractions calculated from a 4-fraction schedule of either radiation type alone produce the same level of damage within the limits of accuracy of the experiment.
微集落测定技术已被用于测试将14兆电子伏中子和γ射线每次分割的等效剂量相加对小鼠肠道损伤的有效性。对于每日分割4次的方案，其中前一或两次分割给予中子，其余给予γ射线，根据单独一种辐射类型的4次分割方案计算出的联合剂量分割在实验精度范围内产生相同程度的损伤。
