Radiography courses in the UK typically take three years to complete when studied full-time at the undergraduate level. This applies to diagnostic radiography, which involves creating medical images of the body using X-rays, and therapeutic radiography, which uses radiation to treat cancer and other medical conditions. Some universities also offer part-time and accelerated options for radiography courses. It may take longer or shorter periods to complete depending on the specific program structure. It's worth noting that the course length may also vary depending on the university and the level of study (undergraduate or postgraduate), so it's always important to check the specific course details before applying.
