Which type of cancer has a risk multiplier of 1.4x due to radiation exposure?

• A. Skin cancer
• B. Brain cancer
• C. Colon cancer
• D. Lymphoma

Answer: (A)

The correct answer is skin cancer, which has a risk multiplier of 1.4x due to radiation exposure. Skin cancer is particularly sensitive to radiation, primarily because ultraviolet (UV) rays from the sun and artificial sources can directly damage the DNA in skin cells, leading to mutations that can result in cancer. The 1.4x risk multiplier indicates that individuals exposed to radiation have a 40% higher risk of developing skin cancer compared to those who are not exposed.

Understanding how radiation affects skin cells is critical as it informs safety measures and exposure guidelines for firefighters and first responders who may encounter hazardous materials that involve radiation. It is essential to implement protective measures in order to limit exposure and reduce the risk of developing skin cancer, making knowledge about this risk multiplier crucial for personal and occupational health.
