If you're not feeling challenged in your current role, nursing may be an interesting field to explore - there's no shortage of different areas to practice and specialise in, and it's highly portable.
Radiography has more office like hours, which can be good if you want that stability and regular family time. However, there's a lot less continuity in patient care, which I would find unsatisfying - I enjoy seeing patients getting better, or making their dying more comfortable, and having those with chronic diseases come in over a period of years.
Deciding to nurse was the best thing I've done thus far - I've made some of the best friends of my life, earned good money, embraced higher education after swearing off it, and have a job that (after almost two decades) I still enjoy most of the time. It's also given me a better sense of perspective - I'd have a lot of trouble now listening to people carry on about something trivial as though it's life and death.
Hope that helps. Good luck
