According to Camerapedia, typical radiation from these glass elements approaches about 10 milliroentgen per hour (mR/hr) at the lens surface, decreasing to almost undetectable levels by the time you’re as few as 3 feet away. By comparison, a chest X-Ray exposes you to about that same amount, and dental x-rays can expose you to as much as 40 mr/Hr in one sitting.
