Which equipment in a nuclear compounding pharmacy must be lead lined?

In a nuclear compounding pharmacy, the primary concern is the safe handling of radioactive materials. The correct choice highlights that the refrigerator and drawing station must be lead lined to minimize exposure to radiation. Lead is a dense material known for its effectiveness in shielding against gamma radiation and other forms of radiation commonly encountered in nuclear pharmacy operations.

Lead lining in the refrigerator ensures that any radioactive materials stored there do not pose a risk of radiation exposure to pharmacy staff or others nearby. Similarly, the drawing station, where technicians prepare and draw nuclear medication, requires lead lining to protect against radiation that may be emitted during these processes.

The other options do not address the specific safety needs associated with radiation exposure that lead lining provides in key areas of nuclear pharmacy operations. For example, while glassware and countertops are important for proper handling and containment of compounds, they do not inherently need lead linings for radiation protection. Similarly, weighing balances and fume hoods, while important in various laboratory processes, do not typically involve direct exposure to significant levels of radiation that necessitate lead lining.
