You'll find that it is different, very different, from any other setting. Essentially, a majority of your shift is spent compounding kits and drawing doses. There is also quite a bit more paperwork to do than most other settings. Here are some of the pros and cons:
Pros:
Laid back environment, casual dress
Professional communication with nuc med techs and MD's
No narcotics or public to deal with
Many breaks throughout the day
Cons:
Odd hours and rotating weekends
Must take call
Pay is approx. 7-10% less than retail
May be difficult to get hired without authorized user certification
Hope this helps a little.
