Final answer:
The required hours of training to become a Nuclear Pharmacist are not specified in the provided materials, but specialized training beyond the doctorate in pharmacy is needed, typically involving instruction in radioisotope handling.
Step-by-step explanation:
The amount of training that a pharmacist must complete to become a Nuclear Pharmacist is not stated in the provided materials. However, becoming a pharmacist in the United States generally requires obtaining a doctorate in pharmacy which includes four years of education in a specialty pharmacy school. After completing the educational requirements, a pharmacist must also be licensed in the state they wish to practice in. Nuclear pharmacy, being a specialized area within the field of pharmacy, likely requires additional postgraduate training and certification, addressing both the safe handling and proper procedural use of radioactive materials for diagnostic and therapeutic purposes. The American Pharmacists Association (APhA) provides specific guidelines on the requirements for becoming a board-certified Nuclear Pharmacist, which includes a minimum of 500 hours of instruction in basic radioisotope handling techniques specific to the use of unsealed radioactive material in medicine, among other requirements.
