Does anyone know where I can find guidance on x-ray exclusion zones. We are developing our manufacturing facility which will include a fixed welding station and need to understand the exclusion zones required for x-raying to inform the layout of the surrounding areas. Thanks, Richard

Thats good advice. You also need to inform the HSE if using such a device.

You definitely need the advice of a Radiation Protection Adviser. X-ray equipment is generally operated within a shielded enclosure with interlocked doors. The enclosure might be tiny for a desktop X-ray machine, or it may be a whole room for a large industrial X-ray setup. If you are using it to X-ray welds it is more likely to be a room-sized enclosure. We cannot go further than that, because the shielding required, or safe distance required, depends on a whole host of parameters, and it would not be sensible to even try to do this through the medium of a forum. You can get the services of a Radiation Protection Adviser relatively easily - organisations such as the Health Protection Agency provide the service. They will be able to discuss with you the type of machine you intend to purchase and how it should be installed. https://www.hpa-radiationservices.org.uk/rpa is a good start.

You could try L121 - Work with ionising radiation - Ionising radiation Regulations 1999 - Approved Code of Practice and Guidance free to download from HSE books.

Please remember that all Radiation Protection Advisors/inspectors etc are appointed by the Government. I use one employed at Sussex University. Rich
