This is good practice questions. However, they seem quite focused on therapeutic radiology (radiation therapy) which makes me wonder if the questions are for part 2 exam and not the general physics (part 1) exam. Does anyone know?
You are correct Jens. These are typical ABR therapy questions (2nd part written). Generally part 1 of the ABR exam covers some basic (elementary) topics on nuclear medicine, diagnostic physics, therapy physics, radiation safety, shielding, instrumentation and biology. Hope we get some sample questions for part 1 and part 2 of diagnostic physics in this blog. The questions seem challenging ones!
Hey everyone, I am trying to figure out what I should be studying to get ready for part one of the Radiation Oncology Physics test next year. Do you have any suggestions? I know part one is more general than part 2 and thats what concerns me.
any info would be appreciated.
thanks

I am wondering if there is a good review course for parts 1 and 2 of ABR exam with a concentration in nuclear medicine. I am taking the exam August 2010 and could use a refresher.
Chuck, Good question. I’ll check around. If I hear of such a course, I will certainly post the info. In the meanwhile, you can always start your prep with a good text. Check out “Physics in Nuclear Medicine” by Simon Cherry et al.
