What is the main concern when disposing of Tc-99m wastes?

• A. Minimizing chemical reactions
• B. Radioactive contamination and safety compliance
• C. Reducing costs of disposal methods
• D. Ensuring waste is biodegradable

Answer: (B)

The primary concern when disposing of Tc-99m waste is radioactive contamination and safety compliance. Tc-99m is a radioactive isotope used extensively in various medical imaging procedures. When handling and disposing of materials that contain this isotope, it is crucial to adhere to strict regulatory guidelines to ensure the safety of healthcare workers, patients, and the environment.

Radioactive waste must be managed to prevent the potential release of radiation to the surrounding area, which can have serious health implications. Compliance with safety protocols and proper disposal methods are essential to mitigate the risks associated with exposure to radioactive substances. This includes following guidelines set by agencies such as the Environmental Protection Agency (EPA) and the Nuclear Regulatory Commission (NRC), which outline the safe handling, storage, and disposal of radioactive materials.

Other factors like minimizing chemical reactions, reducing costs, or ensuring biodegradability may be considerations in waste management but are secondary to the overarching need to prevent radioactive contamination and to comply with safety regulations. The management of radioactive waste centers primarily on maintaining safety and protecting public health.
