The Society and College of Radiographers represents more than 90 per cent of the working radiographers in the UK. It is responsible for their professional, educational, public, and workplace interests. As an organization, the Society is probably unique, being both a professional body and a trades union affiliated to the Trades Union Congress. Founded in 1920, the Society is one of the oldest and most experienced radiography bodies in the world. The College is the charitable subsidiary of The Society and it exists to serve the public good. The College's objects are directed towards education, research, and other activities in support of the science and practice of radiography and its allied sciences. The Society commissions the College to deliver professional and educational services on behalf of members and the general public.
