From Point Sources to Phantoms: Refining Dose Rate Models in Nuclear Medicine with Tc-99m, F-18, I-131 and Lu- 177

2025-12-05

Abstract excerpt

<title>Abstract</title> <p>Healthcare workers in nuclear medicine (NM) are often exposed to external radiation from patients who have been administered radiopharmaceuticals, particularly during procedures requiring close contact. Traditional dose rate estimates commonly assume patients to be unattenuated point sources and apply inverse square law calculations, which tend to overestimate exposures at clinical dist...
