This document constitutes the final report of Task 1 of the project Xenon International Paper Study, performed under a Pacific Northwest National Laboratory (PNNL) contract. In this report we present the outcome of studies performed to increase the understanding on how the network of radioxenon measurement stations, being a part of the the international monitoring system (IMS) for verification of the Comprehensive Nuclear-Test-Ban Treaty, is affected by network and measurement station parameters. The study was performed by analyzing the network response to a synthetic data set of concentration profiles from a large number of sources of radioxenon releases with compositions characteristic of nuclear explosions. The response was studied for different model radioxenon systems populating the network. In addition, the dependence of system level performance indicators on actual system parameters was modelled.
