N2 - We performed a field study of eye lens dosimetry for workers involved in the decommissioning operation at the Fukushima Daiichi Nuclear Power Plant. In this study, humanoid phantoms equipped with different personal dosemeters were placed at selected locations in the workplace. The experiment showed that Hp(3) at the head is about 20% higher than Hp(10) (or Hp(3)) at the trunk. This level of dose gradient is generally interpreted as being “almost uniform” in radiological control; therefore, tasks conducted in open areas with such relatively small dose gradients (~1.2) will not require specific monitoring with eye lens dosemeters, except when the eye lens dose approaches the dose limit.
