NGET Generic Radiation Worker Practice Test

Organ-specific dose limits are set because different parts of the body have different sensitivities and protection goals. The whole-body TEDE limit is a general cap for the entire body, while the lens of the eye has its own dose limit. The eye-lens limit is higher than the whole-body limit (for example, around 150 mSv per year for the lens versus 50 mSv per year for TEDE). This means the regulatory limit for the lens can be numerically higher, even though eye protection remains important to prevent cataracts. The other options refer to different tissue limits, but they don’t pertain to the lens’ specific limit.
