If radiation penetrates the human tissue, there is a risk of damage to tissue and organs. Radiation Shielding Glasses RD 50 and RD 30 provide optimum protection, as they contain a high percentage of lead oxide, absorbing the rays. The figure "50" stands for a min. 5,05 g/cm³ density. The figure "30" stands for a min. 3,13 g/cm³ density. Which glass is used depends on the lead equivalent, which is determined for each application. Health protection The Radiation Shielding Glasses RD 50 and RD 30 provide the best protection for: * Technicians monitoring the x-ray process in medicine and industry * Technicians at mammography work stations * Technicians in research and development (i.e. "glove-box")
