How is the lifestyle of a nuclear pharmacist? I heard that some employers require you to take on call.
The lifestyle depends, like retail, on the location itself. In a lab with more than 3 pharmacists, the lifestyle is pretty relaxed and flexible. I currently have on staff 6 pharmacists at my location. I take call one night a week and work 1 week of night shift per month. I also work every 6th weekend. Personally, the benefits of working in a nuclear setting far outweigh the downsides.
Do nuclear pharmacists have the opportunity to work overtime just like retail pharmacists do?
Nuclear pharmacists in my experience have very little opportunity to work overtime at their lab. Many do work outside, in either retail or hospital, for extra income.
I've heard stories that some pharmacists working with chemo had to be stripped naked when they accidently spilled some chemicals on themselves, does that happen in nuclear pharmacy?
Fortunately, no. Our radiation precautions are very intense. Generally speaking, if someone spilled some radioactive material on their lab coat, they would simply remove the lab coat and put the lab coat in the decay area. If radioactive material ever got on someone's skin, such as a needle-stick, we have procedures in place to effectively deal with this.
