Detailed explanation-1: -Radiation of certain wavelengths, called ionizing radiation, has enough energy to damage DNA and cause cancer. Ionizing radiation includes radon, x-rays, gamma rays, and other forms of high-energy radiation.
Detailed explanation-2: -High energy (ionising) radiation can cause cancer if a person is exposed to a lot of it. This is because it can affect our cells and damage our DNA. Ionising radiation is different to the radiation given off by mobile phones, 4G and radios. These sources use much lower energy radiation and don’t cause cancer.
Detailed explanation-3: -Studies have linked radiation therapy to treat cancer with an increased risk of leukemia, thyroid cancer, early-onset breast cancer, and some other cancers later in life. The increase in risk depends on a number of factors, including: The dose of radiation.
