Interactive software automates personalized radiation safety plans for Na131I therapy

Area of Science:

• Nuclear Medicine
• Radiation Safety
• Medical Physics

Background:

• Nuclear Regulatory Commission (NRC) regulations permit patient release with liberalized criteria after radioactive material administration.
• Written radiation safety instructions are mandatory if others may receive over 1 millisievert (mSv).
• Existing NRC guidance lacks specifics on dose minimization strategies and duration of restrictions for patients treated with Na131I.

Purpose of the Study:

• To develop and evaluate interactive software for creating patient-specific radiation safety plans.
• To facilitate compliance with NRC regulations by calculating expected radiation doses to others.
• To aid in minimizing radiation exposure to family and caregivers of patients treated with Na131I.

Main Methods:

• Development of interactive software with a graphic interface displaying daily and cumulative effective exposures.
• Patient interviews to input proposed daily contacts and interactions.
• Point-and-click operation for entering individual contact details and real-time dose accumulation and modification.

Main Results:

• The software generates tailored radiation safety recommendations based on clinical, dosing, and social situations.
• Dose estimates are calculated and adjusted dynamically during contact schedule negotiation.
• The software has been successfully used with over 100 patients, proving highly useful and well-received.

Conclusions:

• The developed software effectively supports the creation of personalized radiation safety plans for patients treated with Na131I.
• It aids in meeting NRC regulatory requirements and proactively managing radiation safety for the public.
• The tool enhances patient care by providing practical, user-friendly guidance for minimizing radiation exposure to others.
