WebApr 11, 2024 · The mean effective doses were 13.44 ± 4.05 mSv and 6.07 ± 3.40 mSv, respectively, and the mean SSDEs were 13.84 ± 2.94 mGy and 5.69 ± 2.27 mGy, respectively. The high-spike CT protocol without ECG monitoring reduced the radiation exposure by 55% compared to the protocol with ECG monitoring (from 13.44 mSv to 6.07 mSv). WebThese calculations showed that the highest dosage which would have been received from persistent radioactivity at Hiroshima was between 6 and 25 roentgens of gamma radiation; the highest in the Nagasaki Area was between 30 and 110 roentgens of gamma radiation.
