title: Evaluation of Ludlum Corporation's portable portal monitor and comparison with the HML'S existing portal monitors.
abstract: 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.
