Is eye lens dosimetry needed in nuclear medicine?

Introduction. The exact level of exposure experienced by nuclear medicine personnel, whose work
often requires performing manual procedures involving radioactive isotopes, is associated with the
form of radiation source used. The variety of radionuclides and medical procedures, and the yearly
increase in the number of patients, as well as the change of the individual dose limit for the lens
of the eye from a value of 150 mSv yr −1 to 20 mSv yr −1 , mean that issues of eye lens routine
dosimetry become interesting from the radiation protection point of view. Objective. This paper
presents an analysis of the exposure of the eye lenses of nuclear medicine department personnel, as
well as those of personnel in the facilities that produce radiopharmaceuticals for the purpose of
diagnosis by positron emission tomography, from the viewpoint of the advisability of routine eye
lens exposure monitoring, taking into account changes in the dose limit for th...
