All sites using radionuclides in research or manufacture are strictly regulated by external authorities. These controls embrace the transport, packaging, handling, storage and use of radioisotopes and the management of residues from the production process. All the company's nuclear licensed sites comply fully with the strictly set legal limits for safe discharges and waste storage.

The company has also been investing in new technologies and techniques to improve its radioactive waste management procedures. These include reducing wherever possible the amount generated and storing or disposing of residues to the highest standards. In the UK, this led the company to invest in its own state-of-the-art facility for storage of intermediate level waste until a Government approved facility is constructed.
