Device for Sensing a Radiation Dose Incident on an Eye Lens

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention relates to an advanced device, specifically an active dosimeter, for sensing and measuring the radiation dose that reaches the lens of the human eye in real time. The device uses an electronic detector system with sensor elements designed to closely mimic the actual radiation exposure of the eye, even when personal protective equipment such as leaded glasses is used. It features means (such as filters or absorbers) that attenuate or simulate the shielding effect of protection gear, providing an accurate assessment of the radiation dose actually received by the eye. The system can detect both the energy and angle of incoming ionizing radiation, works with various types of sensors, and can be integrated into eyewear or headgear. It also offers features like wireless data transmission, user-specific data storage, and instant dose or warning displays to the wearer.

Use CasesContent extracted from patent full text and abstract with AI.

• Radiation safety monitoring for medical personnel during interventional radiology, cardiology, neurosurgery, orthopedics, or trauma surgery, where eye lens dose limits can be exceeded.
• Dosimetry and compliance monitoring in nuclear power plants, research labs, or any workplace with potential ionizing radiation exposure risks to the eyes.
• Real-time personal dosimetry for workers in industrial radiography or non-destructive testing.
• Monitoring and optimizing eye protection effectiveness for healthcare practitioners required to wear leaded glasses or similar PPE.
• Educational and training tools for radiation safety programs, demonstrating dose accumulation and hazard localization.
• Personal monitoring for compliance with stricter regulatory standards for occupational lens dose limits.

BenefitsContent extracted from patent full text and abstract with AI.

• Provides real-time measurement and display of actual lens dose and dose rate, unlike passive dosimeters that require post-use processing.
• Enables immediate feedback to the wearer, allowing on-the-spot behavioral or protective changes to reduce exposure and prevent radiation-induced cataracts.
• Accurately accounts for protective eyewear/shielding so the measured dose reflects the true lens exposure, enhancing safety compliance.
• Detects both the amount and direction (angle) of incoming radiation, helping to identify positional risks and allowing targeted risk mitigation.
• Highly configurable and adaptable—can be worn as an accessory to protective glasses, headbands, or other headgear for maximum comfort and practicality.
• Allows wireless data transmission, user-specific data logging, and easy sharing or storage of dose records for audits or health monitoring.
• Device modularity allows for easy adaptation to different users, protection equipment, or measurement settings by swapping filter/attenuation modules.
• Helps organizations comply with recently lowered eye lens dose limits, reducing occupational health risks and legal liabilities.
