Effectiveness of shielding materials against 177Lu gamma rays and the corresponding distance relationship

ConclusionsAchieving a reduction of 95% or more requires the 0.25  mm lead equivalent for a distance of 100 cm, the 0.35 mm lead equivalent for 50 cm, the TCR thickness of 0.3 mm for 100 cm, or the TCR thickness of 0.9 mm for 50 cm. Without wearing a protective apron, a reduction of approximately 95% is observed at distances greater than 100 cm. These fin dings would be useful for medical staff engaging in related activities.
