Which of the following is NOT a potential somatic effect of radiation?

Cystic fibrosis is a genetic disorder caused by mutations in the CFTR gene and is not related to radiation exposure or its effects. It primarily affects the respiratory and digestive systems due to the production of thick mucus, leading to various health complications. In contrast, the other options—skin burns, radiation sickness, and hair loss—are well-documented somatic effects that can result from exposure to high doses of radiation. Skin burns can occur due to localized radiation exposure, radiation sickness is a serious condition that manifests due to whole-body exposure to high radiation levels, and hair loss, or alopecia, can result from the effects of radiation on rapidly dividing cells like those in hair follicles. Therefore, the correct answer identifies a non-radiation related condition, distinguishing it from the true somatic effects of radiation.
