True or false: Radiation-induced cataracts can result from a single high dose or from chronic low-dose exposure of the lens.

Radiation-induced cataracts can indeed develop as a result of both a single high dose and chronic low-dose exposure to ionizing radiation of the lens of the eye. The biological effects of radiation on tissues, including the lens, can be cumulative over time.

In the case of a high dose, the resulting cell damage can overwhelm the lens tissue's ability to repair itself, leading to cataract formation. This is particularly relevant in situations where exposure occurs in a single event, such as during some medical imaging procedures or radiation therapy.

Chronic low-dose exposure also poses a risk, as the cumulative effect of multiple low doses can lead to significant cellular damage or changes over time. Such chronic exposure can gradually lead to the disruption of normal lens function and structure, contributing to the development of cataracts.

Understanding the effects of both high and low doses of radiation on eye health is critical for individuals working in fields that expose them to ionizing radiation, enabling them to take appropriate safety precautions to minimize risks.
