Contamination Resulting From a Broken 125I Seed During a Brachytherapy Procedure

Area of Science:

• Medical Physics
• Radiation Oncology
• Nuclear Medicine

Background:

• Brachytherapy programs require strict radiation safety protocols for staff and patient protection.
• Standard training covers radioactive sources, emergency procedures, and regulatory requirements for radioisotopes.
• Brachytherapy typically uses sealed sources, minimizing contamination risks during routine operations.

Purpose of the Study:

• To present an unusual clinical incident involving a damaged Iodine-125 (125I) brachytherapy seed.
• To highlight the resulting radioactive contamination within a clinical environment.
• To identify shortcomings in existing radiation safety programs regarding contamination preparedness.

Main Methods:

• Case report of a clinical incident.
• Analysis of the incident's impact on the clinical environment.
• Review of the radiation safety program's response and training protocols.

Main Results:

• A damaged 125I brachytherapy seed led to unexpected radioactive contamination.
• Decisions made during the incident resulted in the spread of contamination beyond the initial site.
• The incident exposed a lack of preparedness for handling unsealed radioactivity in brachytherapy staff.

Conclusions:

• Brachytherapy radiation safety programs must include specific training for radioactive contamination incidents.
• Enhanced emergency training is crucial to equip staff for unexpected damage to sealed radioactive sources.
• Preparedness for contamination events will strengthen overall radiation safety in brachytherapy.
