I had a contrast-enhanced CT scan of my abdomen. How much radiation was there?

The radiation is relatively large! , and it’s very harmful! According to Public Health, relevant experts have reminded that children should try to avoid CT scans because the long-term risk of cancer caused by 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 adult radiation doses are used on newborns or young children, the dose effect increases by more than 50%. This is because the central dose for large objects (adults) is half the surface dose, while for small objects (children) the central dose is almost the entire surface dose. For common lung diseases in newborns, chest X-rays can suffice for diagnosis unless there are special circumstances. Although multi-slice spiral CT examination is good at displaying lung lesions, the damage caused by its high radiation to the newborn's body may exceed its value in disease diagnosis. Therefore, chest diseases are common in newborns, and CT is generally not necessary. In particular, repeated CT scans for newborns should be prohibited in a short period of time. _Elf Children's Network recommends that you have an MRI if you have the conditions; because too many CT "shots" will increase the incidence of cancer. CT examination is actually a kind of X-ray examination. The radiation of CT is ionizing radiation. Excessive ionizing radiation may cause cancer to the human body. Ionizing radiation can damage the structure of DNA in human cells. Some damaged DNA can be repaired, but too much or severely damaged DNA cannot be repaired. In this way, genes will change, creating cancer cells and causing cancer. The annual radiation dose to an individual from the natural environment is about 3mSv (milliSv), and the radiation dose from one abdomen, spine or whole-body CT is about 10mSv, which is the total radiation dose in the natural environment for three years; one chest CT is equivalent to The amount of radiation a person receives over two years, the radiation dose of head and heart CT is smaller, only 2mSv at a time. When CT examinations are repeated multiple times, the radiation dose and corresponding harm can accumulate, and the incidence of cancer may increase.
