Ionising radiation is commonly used in a wide range of industries, and companies that do so are required to protect workers, the public and the environment from their potentially harmful effects. Through our comprehensive range of services, we will ensure your practices are justified, safe, comply with all relevant legislation and are fit for purpose.
As Europe's leading commercial provider of radiation protection services, Nuvia offers support, consultancy and expertise in all aspects of radiation protection and the characterisation of radioactive materials.
We supply these services to a wide variety of customers including those in the oil and gas sector, nuclear industry, government agencies, global corporations and small private companies using radiation in a variety of technologies.
Our tailored professional radiation protection advisory service is available to clients big and small who work with ionising radiation.
We help clients to comply with all statutory obligations by providing radiation protection advisers (RPAs), who can be integrated into existing project teams and will ensure that all work - from small movements of radioactive materials to large-scale engineering operations - takes place within a robust system of radiological protection.
In accordance with the Ionising Radiations Regulations 2017, the RPA2000 HSE-approved assessing body has accredited all of our RPAs. A number of our RPAs are also appointed Radioactive Waste Advisers (RWAs).
The Ionising Radiations Regulations 2017 (IRR17) place a legal requirement on all employers to ensure that all workers engaged in work with ionising radiation receive appropriate radiation protection training.
Nuvia's range of safety training courses has been specifically developed to meet the demands of the regulations and the needs of clients. Qualified, experienced radiation protection advisers lead all courses, meaning delegates benefit from practical experience in working with and advising on ionising radiation.
Training courses provided include:
- Basic radiation protection
- Radiation Protection Supervisor
- BRP and RPS Refresher
- X-ray radiation protection
Training can be undertaken on your own premises or at any of our sites, including Aberdeen, Dounreay, Harwell, Risley, Sellafield, Westlakes and Winfrith, and we also run courses further afield for our international clients.
