Field test results of an automated exposure assessment tool, the local positioning system (LPS)

Abstract

A user-friendly environmental monitoring system that collects real time data has been developed. Flash card memory logs exposure data from multiple sensors along with corresponding times and positions. Optional use of telemetry repeaters and a reference station allows central monitoring of data to assess exposure and to initiate intervention when safe levels are exceeded. A software analysis package allows researchers to identify exposure hot spots and direct control efforts, with the ultimate goal being to reduce injury and disease. Preliminary field test results document position accuracy and system performance in harsh environments.
