Since the Human Monitoring Laboratory compared two types of portal monitors (the P3 and the MiniSentry) that could be field deployed in response to an emergency, two more brands have been added to the inventory. This paper summarizes a comparison of the capabilities of the previous portal monitors with the two additions: the Thermo Eberline TPM-903B and the Ludlum 52-1-1. The comparison shows that none of the portals greatly exceed the others in capability, but that each will have their place during emergency deployment; however, when beta radiation or low energy gamma radiation is suspected, then the best choice would be the Ludlum 52-1-1.
由于人类监测实验室比较了两种可现场部署以应对紧急情况的门户监测器（P3 和 MiniSentry），库存中又增加了两个品牌。本文总结了之前的门户监测器与新增的两个品牌：Thermo Eberline TPM-903B 和 Ludlum 52-1-1 的性能比较。比较表明，没有一个门户在性能上大大超过其他门户，但在紧急部署时，每个门户都有其用途；然而，当怀疑存在β辐射或低能γ辐射时，最佳选择将是 Ludlum 52-1-1。
