One test option recommended by the EPA for deciding to mitigate involves up to two short-term measurements. If the initial measurement is > or = 148 Bq m-3, the test is repeated and the house is mitigated only if the mean of the two measurements is > or = 148 Bq m-3. The frequency of errors under this test option was evaluated using 2-d and 1-y measurements from 1,449 houses. The chances of making incorrect mitigation decisions vary from 1% to more than 50%.
美国环境保护局（EPA）推荐的一种用于决定是否进行缓解措施的测试选项涉及最多两次短期测量。如果初始测量值≥148贝克勒尔/立方米，则重复该测试，并且只有当两次测量的平均值≥148贝克勒尔/立方米时，才对房屋采取缓解措施。使用来自1449所房屋的二维和一年期测量数据评估了该测试选项下的错误频率。做出错误缓解决策的可能性从1%到超过50%不等。
