0.35 mm lead (Pb)
Do use of leaded glasses is recommended for occupational use in medical imaging in
order to prevent which of the following conditions

Radiation induced cataracts
,A radiologist receives an equivalent dose of 100 microsieverts while standing 25 cm
from a patient during a fluoroscopy procedure. Estimate the equivalent dose if the
