The correct answer is: Radiations are harmful as it causes skin cancer.
Radiation is a form of energy that can travel through space and matter. It can be harmful to humans if it is absorbed in high doses. Radiation can cause cancer, damage DNA, and lead to other health problems.
Skin cancer is the most common type of cancer in the United States. It is caused by exposure to ultraviolet (UV) radiation from the sun or from artificial sources, such as tanning beds. UV radiation can damage the DNA in skin cells, which can lead to the development of cancer.
There are three main types of skin cancer: basal cell carcinoma, squamous cell carcinoma, and melanoma. Basal cell carcinoma is the most common type of skin cancer and is usually not life-threatening. Squamous cell carcinoma is more serious than basal cell carcinoma, but it is still usually treatable. Melanoma is the most serious type of skin cancer and can be life-threatening.
The best way to prevent skin cancer is to avoid exposure to UV radiation. This means wearing sunscreen with an SPF of 30 or higher, wearing protective clothing, and avoiding the sun during the middle of the day when the sun’s rays are strongest.
If you have any concerns about skin cancer, talk to your doctor.
The other options are incorrect because:
- Radiation does not cause anemia. Anemia is a condition in which the body does not have enough healthy red blood cells. It can be caused by a number of things, including iron deficiency, vitamin B12 deficiency, and sickle cell anemia.
- Radiation does not always alter body tissues. The effects of radiation on the body depend on the type of radiation, the dose of radiation, and the length of time the person is exposed to radiation.
- Radiation is not always unstable. Some types of radiation, such as alpha particles and beta particles, are unstable and can decay into other forms of radiation. However, other types of radiation, such as gamma rays and X-rays, are stable and do not decay.
