Use Lead Glasses To Protect Your Eyes

1. Use Lead Glasses To Protect Your Eyes Protecting Your Eyes from Ionizing Radiation Exposure Lead shielding is an important radiation safety principle. In fact, shielding is one of the three basic radiation safety principles. Time, distance and shielding are the primary means of eliminating or reducing ionizing radiation exposure. Lead Shielding Shielding should be used wherever it is necessary to reduce or eliminate radiation exposure. There are a variety of types of lead shielding options, the focus of this article will be on radiation eye protection and the use of lead glasses. Radiation Attenuation Appropriate shielding placed between the source of radiation and the worker, radiation is attenuated and exposure may be completely eliminated or reduced to an acceptable level. Lead acts as a barrier to reduce x-ray’s effect by blocking or bouncing particles through a barrier material. Attenuation is the result of interactions between x-ray and matter that include absorption and scatter. Much like lead aprons which are commonly found in x-ray rooms in hospitals, lead glasses reduce radiation exposure and protect the lens of the eye. Occupational Radiation Exposure Limits Exposure limits have been established by the Nuclear Regulatory Committee (NRC) and set to a level where apparent injury due to ionizing radiation during a normal lifetime is unlikely. This limit is called the “maximum permissible exposure” and medical personnel should be aware of their occupational radiation dose. These occupational radiation exposure limits have been established to help minimize the amount of radiation a worker receives annually by monitoring their occupational radiation dose and keeping them under the established limits. “The exposure limit for the whole body (5,000 mrem) is lower than that for a single organ because all organs and tissues are exposed in whole body exposure, while only a single organ is involved in the single organ exposure limits.”

2. Personal Monitoring The U.S. Nuclear Regulatory Commission has requirements regarding personal monitoring devices. Many medical personnel are required to wear an individual monitoring device to measure the dose to the whole body as well as one at an unshielded location closer to the eye to provide an accurate reading of the lens dose equivalent. Wearing lead glasses will help ensure the lenses of the eyes are properly protected from ionizing radiation thereby reducing your risk of developing cataracts. “Radiation workers who operate x-ray machines, fluoroscopy units, certain unsealed and sealed radioisotopes or are exposed to other sources of gamma or high energy beta radiation are generally required to wear one or more dosimeters.” Eye Protection: Reducing Tissue Reactions Tissue reactions, previously referred to as deterministic effects or non-stochastic effects, describe a cause an effect relationship between radiation and some side- effects. There is a threshold dose, once exceeded, the severity of an effect increases with dose. Examples of tissue reactions include skin erythematic, which can occur shortly after radiation exposure. Late tissue reactions, particularly those involving the lens of the eye, such as cataracts, can develop long after the initial radiation exposure, but still can be traced back to the original exposure. Lead Glasses Today, lead glasses come in a wide-variety of styles and configurations including wraparound, goggles, fit over, economy, plastic, metal, and designer frames. For example, metal frames are available with frontal (lens) and lateral radiation(side shields) protection offering 0.75mm and 0.35mm lead (Pb) equivalency respectively. The industry standard 0.75mm lead equivalency SCHOTT SF6 radiation safety glass lenses provide protection from harmful radiation exposure. The lenses have been tested (CE Certified for Radiation Reducing Eyewear) at 100 kV and have a nominal lead equivalence of 0.75mm Pb and the side shields offer a nominal lead equivalence of 0.35mm Pb at 100 kV.
