Radiochemistry


The NIRAS radiochemistry facility consists of 20 self contained laboratories dedicated to the different facets of the sample analysis process with completely segregated suites for suites for  ‘active’ and ‘environmental’ analysis to avoid cross contamination.  All assessment is undertaken in segregated radiometric counting laboratories.  The facility has a state of the art LIMS (Laboratory Information Management System) to record and track all sample data and analysis information sample arrival to report and archiving.

NIRAS offers a comprehensive chemical and radiochemical analysis services on radioactive or potentially radioactive samples, dealing with non-standard, non-routine radiochemical analysis in the consultancy field.
