Lead Codes – get to know the codes and equivalences

Lead codes, what are they?

Many of our customers frequently ask us about lead codes with regards to their x-ray protection requirements. With this in mind we wanted to help you get to know lead codes and their equivalences.

Depending on the application, radiation source output, and the layout of the environment, various lead thicknesses will be required to ensure appropriate x-ray protection. Commonly, lead sheeting is used for x-ray protection due its high density. Although there may be denser materials, lead is used because it is cost effective and readily available.

So what does the term ‘Lead Code’ mean?

Lead code determines the thickness of the lead. As the code lead gets higher, so does the thickness. The higher the thickness, the more dense material there is to provide protection from the radiation source. Although there is no limit to the depth of lead for radiation protection, commonly, in the UK lead codes for x-ray protection range from code 3 to code 8.

Commonly Used Codes

Code 3 – Veterinary and Dental applications
Code 4 – X-ray rooms
Codes 5 & 6 –  CT rooms.

Here is a chart to use when referring to lead codes and lead thicknesses.
