What safety precautions must be taken when handling Technetium-99m?

• A. No specific precautions are necessary
• B. Use of gloves and proper disposal of radioactive waste
• C. Only wearing a lab coat is required
• D. Keeping the substance in an open area

Answer: (B)

Using gloves and ensuring the proper disposal of radioactive waste are essential safety precautions when handling Technetium-99m. This radioisotope is widely used in medical imaging; however, it emits radiation, which can pose health risks if proper safeguards are not followed.

Wearing gloves protects the skin from contamination, which could occur if Technetium-99m particles come into contact with hands during preparation or administration. This also minimizes the risk of transferring radioactivity to other surfaces or individuals. Proper disposal of radioactive waste ensures that any materials contaminated with Technetium-99m are handled according to regulatory guidelines, preventing environmental contamination and reducing exposure to personnel who may handle or come into contact with waste materials.

This multifaceted approach to safety is critical in radiopharmaceutical practice, where minimizing radiation exposure is paramount for the safety of healthcare staff and patients alike. Other options, like relying solely on a lab coat or not taking any specific precautions, do not adequately protect against potential hazards associated with radioactive materials.
