Transcript of Electromagnetic Radiation- CT Scans. By Alice Neill CT Scans When were CT Scans invented? Limitation of the technology and a Summary of an article Bibliography CT Scans were invented in in 1972 by a British engineer, Godfrey Hounsfield and South African-born physicist Allan Cormack. They were both independently developed in England and in the US.
A CT scan can deliver anywhere from 2 to 10 millisieverts of radiation, depending on what type of scan a patient receives. For exams requiring multiple scans, this can add up to 20-30 milliSieverts, but this is still considered a low dose of radiation.For some, scans, such as a head CT, the exposure is very low, about 1 - 2 milliSieverts.Because children have a longer life expectancy than adults and some of their tissues are more sensitive to radiation that for adults, we are particularly careful to use lower doses in children.or some, scans, such as a head CT, the exposure is very low, about 1 - 2 milliSieverts.
