Summary

Radiation exposure from gallium-67 citrate (67Ga-citrate) patients to staff is minimal. Routine care and imaging tasks do not require special precautions for medical personnel handling these patients.

Area of Science:

  • Nuclear Medicine
  • Radiopharmacology
  • Radiation Safety

Background:

  • Gallium-67 citrate (67Ga-citrate) is used in diagnostic imaging, particularly for lymphoma.
  • Assessing radiation exposure from patients to healthcare personnel and family is crucial for safety protocols.

Purpose of the Study:

  • To determine the radiation exposure levels for individuals in proximity to patients administered with 67Ga-citrate.
  • To estimate radiation doses for radiology and nursing staff during patient care and imaging procedures.

Main Methods:

  • Serial radiation monitoring of 15 adult patients post-injection of 67Ga-citrate.
  • Dose rate measurements at various distances and projections using a calibrated ion chamber.
  • Analysis of contact times for routine nursing and radiology tasks.

Main Results:

  • Mean instantaneous exposures were determined for a standard administered activity of 370 MBq (10 mCi) 67Ga-citrate.
  • Maximum patient contact time within 30.5 cm was found to be 30 minutes during routine procedures.

Conclusions:

  • Quantified radiation exposure scenarios indicate no special precautions are needed for medical personnel during routine tasks with 67Ga-citrate patients.
  • Radiation safety protocols for 67Ga-citrate administration can be maintained with standard practices.
