摘要本工作的目的是应用蒙特卡罗方法（GUMS 1）评估电磁场测量中的不确定度，并将结果与使用“标准”方法（GUM）获得的结果进行比较。特别是，这两种方法被应用，以评估现场测量不确定度使用频率选择性辐射计和总暴露商（TEQ）的不确定性。比较结果，以突出的情况下，GUMS 1的结果偏离显着从使用GUM，如存在的非线性数学模型连接的输入与输出量（TEQ模型的情况下）或存在的输入量的主要非正态分布（U形失配不确定性的情况下）。从这两种方法获得的结果的偏差甚至可能导致关于是否符合接触参考水平的不同决定。
Abstract The objective of the present work is the application of the Monte Carlo method (GUMS1) for evaluating uncertainty in electromagnetic field measurements and the comparison of the results with the ones obtained using the 'standard' method (GUM). In particular, the two methods are applied in order to evaluate the field measurement uncertainty using a frequency selective radiation meter and the Total Exposure Quotient (TEQ) uncertainty. Comparative results are presented in order to highlight cases where GUMS1 results deviate significantly from the ones obtained using GUM, such as the presence of a non-linear mathematical model connecting the inputs with the output quantity (case of the TEQ model) or the presence of a dominant nonnormal distribution of an input quantity (case of U-shaped mismatch uncertainty). The deviation of the results obtained from the two methods can even lead to different decisions regarding the conformance with the exposure reference levels.
