Performance of the DOSIRIS ™ eye lens dosimeter

Monitoring and protecting of occupational eye doses in interventional radiology (IR) are very
important matters. DOSIRIS ™ is the useful solution to estimate the 3 mm dose-equivalent (Hp(3)), and
it can be worn behind lead glasses. And DOSIRIS ™, adjustable according to 3 axes, it is ideally
placed as close to the eye and in contact with the skin. So, DOSIRIS ™ will be suitable eye lens
dosimeter. However, the fundamental characteristics of the DOSIRIS ™ in the diagnostic x-ray energy
domain (including that of IR x-ray systems) remain unclear. Here, we evaluated the performance of
the dosimeter in that energy range. As a result, the DOSIRIS ™ has good fundamental characteristics
(batch uniformity, dose linearity, energy dependence, and angular dependence) in the diagnostic
x-ray energy domain. We conclude that the DOSIRIS ™ has satisfactory basic performance for
occupational eye dosimetry in diagnostic x-ray energy settings (including IR x-ray systems).
