Do medical radiation from X-rays and CTs have terrible consequences?

Of course there are hazards, and they are significant! According to Popular Health, experts on the subject warn that children should avoid CTs as much as possible, because the long-term risk of cancer associated with a CT diagnosis is higher in children than in adults.　Children are more than 10 times more sensitive to the effects of radiation than adults, and girls are more sensitive to radiation than boys. When an adult radiation dose is applied to a newborn or young child, the dose effect rises by more than 50%.　This is due to the fact that the center dose for a large object (adult) is half the surface dose, whereas for a small object (child) the center dose is almost the entire surface dose.　For common lung diseases in newborns, X-ray chest radiographs are sufficient for diagnosis in the absence of special circumstances. Although multislice CT shows lung lesions well, the high radiation dose to the neonate's body may outweigh its diagnostic value. Therefore, CT is generally not necessary for common chest diseases in newborns, and especially repeated CT examinations within a short period of time should be prohibited in newborns. The first thing you need to do is to take a look at the CT scan, which is actually an X-ray scan, and the radiation from the CT scan belongs to ionizing radiation, which can cause cancer. Ionizing radiation can damage the structure of DNA in human cells. Some damaged DNA can be repaired, but too much damaged and severely damaged DNA cannot be repaired. In this way, genes can change, producing cancer cells and cancer. The annual radiation dose from the natural environment to an individual is about 3mSv (millisieverts), while the radiation dose of 1 abdominal, spinal or whole body CT is about 10mSv, which is the total amount of radiation in the natural environment for 3 years; 1 chest CT is equivalent to the amount of radiation received by an individual for more than 2 years, and the radiation dose of head and heart CT is smaller, and one time is also 2mSv. With many repeated CT examinations, the radiation dose and the corresponding harms The radiation dose and the corresponding hazards can be cumulative, and the incidence of cancer may increase.
