Staff at nuclear medicine departments receive doses of ionising radiation higher 
than the staff of radiotherapy and radiology departments, with the exception of 
interventional radiologists. Due to the updated lower occupational exposure 
limit for the lens of the eye, we measured eye exposure in workers of the 
Nuclear Medicine Department, Pomeranian Medical University in Szczecin, Poland. 
EYE-D™ dosimeters were used for 3 months by 10 employees working with sources of 
ionising radiation. Personal dosimeters also measured the exposure of the whole 
body and hands. The 3-month dose equivalents for the lens of the eye in the 
employees was 0.20-0.72 mSv. Staff at NMD PMU do not require regular routine eye 
lens dose monitoring. Eye lens doses were well within the new annual limit of 20 
mSv. Doses to the whole body may be used as an indicator of the eye lens doses 
in the monitored department.
