Which physical hazard can cause skin cancers and eye cataracts?Group of answer choicesColdX-raysRadonUV rays

Break Down the Problem

1. Identify the physical hazards listed in the question.
2. Determine the effects of each physical hazard on human health, specifically relating to skin cancers and eye cataracts.

Relevant Concepts

• Cold: Generally does not cause skin cancers or cataracts.
• X-rays: Known to be harmful but primarily linked to other forms of cancer rather than skin cancer.
• Radon: A radioactive gas that can lead to lung cancer but not directly related to skin cancers or cataracts.
• UV rays (Ultraviolet rays): Well-documented cause of skin cancers (such as melanoma) and eye cataracts.

Analysis and Detail

• Cold: Exposure to cold temperatures can cause frostbite and other cold-related injuries, but it does not have a direct link to cancer.
• X-rays: While they are ionizing radiation and can increase the risk of certain cancers, they do not specifically cause skin cancers or cataracts.
• Radon: This is primarily a concern for lung cancer due to radioactive decay and prolonged exposure in enclosed areas.
• UV rays: These rays from the sun are well-known for causing DNA damage in skin cells, leading to skin cancer. They also can contribute to the development of cataracts in the eyes due to their capacity to penetrate the skin and eyes.

Verify and Summarize

The only physical hazard among the choices that can directly cause both skin cancers and eye cataracts is UV rays. This conclusion is supported by a significant body of research in health sciences.

Final Answer

UV rays are the physical hazard that can cause skin cancers and eye cataracts.
