Sorry but this is just a long list of questions. I have looked at plenty of career options (2 years remaining until I get my bachelors in physical sciences), and I keep coming back to medical physics as it seems to have everything I want. I haven't decided on the area I would want to specialise in and I don't think I could decide until I had a placement, is this normal or do most students know beforehand? How competitive are places on the training schemes and is it possible to study for a masters with the open university whilst on placement at a hospital? What are the working hours and would I be based at the same hospital all the time? I have read allot about the opportunities to do a PhD part-time but how possible is this when working full time? Finally are most medical physicists satisfied with their careers? I ask this as maybe naively I'm thinking that you do make a difference to peoples lives. Thank you in advance for any replies.
