Many tools for measuring radioactivity are now available on the market, particularly for detecting gamma radiations. These tools are widely implemented on nuclear decommissioning sites, reprocessing facilities or waste repositories.

During nuclear decommissioning or waste management operations, there is a need for imaging the contamination field while identifying and quantifying the contaminants. However, current tools generally provide unprecise measurements and cannot reach the required sensitivity which could optimise current waste segregation practices.

A new generation of portable gamma camera as spectrometer and imager could be here needed. A reliable isotope identification and the ability to quantify radiation (down to N.O.R.M. levels) would likely greatly help for the final release of decontaminated objects or the assessment of field contamination.
