I would look at the FAQ for more details, but I'm happy to share my experience so far (about six months into rads residency).
Highly variable workday depending on the section:
Neuro is mostly reading at the workstation. There is usually one LP, if not two, per day - the the junior residents (i.e. me) are expected to do those. Also, the occasional patient will need sedation for an MRI and if there is not a recent H&P on file, we get to go talk to the patient and get a brief history, make sure they have no allergies to versed (yeah I know), etc. It's a VERY brief history... and it's not like I have to do anything other than sign for the meds, and it's a nice break from the workstation.
MSK is similar... mostly reading at the workstation but usually 1-2 arthrograms per day, also kinda breaks things up a bit. My first month of MSK I only read plain films but subsequent to the first rotation, residents read everything.
Most other rotations is a combo of reading studies, staffing, dictating, answering the phone and explaining interpretations to referring clinicians, etc.
GI is a bit different because much of your day is spent doing the studies you read... i.e., upper GI's, barium enemas, VCUG's, small bowel series... and believe it or not, there is such a thing as a voiding defogram... google it if you don't believe me. I did several during my first month. Usually quiets down in the afternoon and then it is mostly reading abdominal plain films and your morning studies.
Nuclear medicine is also a lot more hands on than I thought. A lot of calls from the techs asking you to check bone scans, make sure additional views aren't needed... check octreotide scans, make sure they got low enough with the tomograms, etc., meeting with patients before/after thyroid ablations, etc.
I don't do US until next week, don't do IR until Feb but our first month on US they try to get us scanning a lot of the time so we kinda get a sense for what the techs do / how they acquire images. IR is busy as hell, frankly. Residents basically get to do as much as they are comfortable with after their first rotation, relatively autonomously.
And, consider I don't even take call yet. We do start working weekends as first years at my program but we have to prelim with another resident since we can't prelim ourselves without getting struck by lightning or something.
Hope that helps.
