Purpose: Radiation protection glasses is a useful tool for dose reduction of eye lens. However, the method to evaluate the dose of eye lens, which is covered with radiation protection glasses in actual radiation management situation, has not been established. We invented the easy-to-use procedure to estimate the dose of eye lens inside of radiation protection glasses for occupationally exposed person using an X-ray shielding material and an additional personal dosimeter for trunk of the body. The objective of this study was to evaluate the feasibility of the new method.
Methods: The radiation field in interventional radiology (IR) was reconstructed. A personal dosimeter was set to the eye position and neck position of medical staff phantom. Each dosimeter was covered by radiation protection glasses or X-ray shielding material, and the 1 cm or 70 mm dose equivalent quantity in the neck position was compared to the 3 mm dose equivalent quantity in the eye position.
Results: The dose equivalent quantity measured inside of X-ray shielding material in the neck position was similar to that of inside radiation protection glasses. Thus, the X-ray attenuation by radiation protection glasses was able to be simulated using the X-ray shielding material.
Conclusion: It was suggested that the dose of eye lens inside of radiation protection glasses could be easily estimated by covering the conventional personal dosimeter for trunk of the body with the X-ray shielding material.

Introduction: Tumor boards are a cornerstone of modern cancer treatment. Given their advanced capabilities, the role of Large Language Models (LLMs) in generating tumor board decisions for otorhinolaryngology (ORL) head and neck surgery is gaining increasing attention. However, concerns over data protection and the use of confidential patient information in web-based LLMs have restricted their widespread adoption and hindered the exploration of their full potential.

Aims: This study aimed to evaluate the principal technical characteristics of a well-type gas-filled ionization chamber dose calibrator used in measuring radiopharmaceutical activity, namely accuracy, repeatability, and linearity. Furthermore, this work also explored the correlation between the device's response and the position and volume of the radiopharmaceutical I-131.
Materials And Methods: Experimental measurements were conducted on the ATOMLAB 500 dose calibrator using NIST traceable Cs-137 source to determine the accuracy and repeatability.

The emergence of mRNA vaccines offers great promise and a potent platform in combating various diseases, notably COVID-19. Nevertheless, challenges such as inherent instability and potential side effects of current delivery systems underscore the critical need for the advancement of stable, safe, and efficacious mRNA vaccines. In this study, a robust mRNA vaccine (cmRNA-1130) eliciting potent immune activation has been developed from a biodegradable lipid with eight ester bonds in the branched tail (AX4) and synthetic circular mRNA (cmRNA) encoding the trimeric Delta receptor binding domain of the SARS-CoV-2 spike protein.

Background: The carbon sequestration potential and water retention capacity of peatlands are closely linked to the growth dynamics of Sphagnum mosses. However, few studies have focused on the response of Sphagnum moss growth dynamics to UV-B radiation, and existing research has emphasized species differences. In this study, Sphagnum palustre L.
