Gamma Excavation Monitor (GEM)

Nuvia offers the full range of services for the characterisation and remediation of land, and the characterisation of waste materials. With over 15 years' experience in both nuclear and non-nuclear sectors, we can provide the experience, expertise and products to meet even the most challenging demands.

GEM is a gross gamma system capable of real-time assay of excavated materials during clearance works. This bulk monitoring system has Environment Agency approval for effective material segregation of volumes up to 1m³.

Capable of measuring and segregating around 350 tonnes of material per day, GEM utilises a battery-operated CsI detector, is calibrated using a mathematical modelling code and all data is instantly downloaded to provide a record of the radioactive inventory and quantities of material.
