Radioactivity services

Accurate measurement of radioactivity

NPL provides customers in the nuclear industry, and suppliers and users of nuclear medicine, with absolute confidence in radioactivity measurements.

Nuclear decommissioning and environmental monitoring

Our services include the supply of standardised radioisotopes for the calibration of customer measurement equipment, calibration of customer-supplied samples, and Proficiency Test Exercises, ensuring industry-wide consistency and accuracy.

We support UKAS accreditation and provide traceability to international standards, providing ultimate confidence in low-level radioactivity measurements and classification of radioactive waste, helping our customers overcome regulatory barriers, and ensure the safety of the general public.

Nuclear medicine

NPL provides radiopharmaceutical and nuclear medicine customers with high purity standardised activity radioisotopes and calibration of customer-supplied samples traceable to NPL primary standards.

Our UKAS-accredited services provide customers with absolute confidence in radioactivity measurements. This increases the safety of radiopharmaceuticals and nuclear medicine administered to patients, improves drug development and ensures regulatory requirements are met.
