Medical physics is an applied area of physics.
I have devoted much time and energy to helping medical physics in developing countries.
I was the Chair of the first department of medical physics in a medical school in the U.S.
When I entered medical physics in 1958 there were fewer than 100 in the U.S. and I could see many opportunities to apply my knowledge of nuclear physics.
The growth of technology is such that it is not possible today for a nuclear physicist to switch into medical physics without training. The field is now much more technical. More training is needed to do the job.
Most medical physicists work in the physics of radiation oncology making sure that the desired dose is given to the cancer and the dose to normal tissues are minimized.
Medical science has proven time and again that when the resources are provided, great progress in the treatment, cure, and prevention of disease can occur.

Physics is like sex: sure, it may give some practical results, but that's not why we do it.
