plants by means of solid-phase extraction with DGA resin. The resin is then used to determine 90 Sr by detection of yttrium-90 ( 90 Y), which exists in secular equilibrium with 90 Sr. The method was tested on 90 Sr-spiked samples (milk) and a certified reference material (IAEA-330), and the trueness values were 108% and 107% for milk, 111% for IAEA-330. In addition, stable Y recoveries exceeded 0.81 in the tests. The ratio of values measured by our examined method and the conventional method ranged from 0.75 to 1.15, and the 90 Sr detection limit ranged from 0.02 to 0.05 Bq/kg fresh weight. The sample-throughput time for the examined method was approximately 3 weeks shorter than that of the conventional method.

Background: In Japan, new regulations that revise the dose limit for the lens of the eye (hereafter the lens), operational quantities, and measurement positions for the lens dose were enforced in April 2021. Based on the international safety standards, national guidelines, the results of the Radiation Safety Research Promotion Fund of the Nuclear Regulation Authority, and other studies, the Working Group of Radiation Protection Standardization Committee, the Japan Health Physics Society (JHPS) developed a guideline for radiation dose monitoring for the lens.Materials and Methods: The Working Group of the JHPS discussed the criteria of non-uniform exposure and the management criteria set not to exceed the dose limit for the lens.Results and Discussion: In July 2020, the JHPS guideline was published. The guideline consists of three parts: main text, explanations, and 26 examples. In the questions, the corresponding answers were prepared, and specific examples were provided to enable similar cases to be addressed.Conclusion: With the development of the guideline on radiation dose monitoring of the lens, radiation managers and workers will be able to smoothly comply with revised regulations and optimize radiation protection.
