WebThe effective dose includes a factor which adjusts for the biological effectiveness of different types of ionizing radiation, e.g. gamma-rays versus neutrons, and sensitivity of different tissues to ionizing radiation. One sievert of ionizing radiation has a biological effect equal to exposure of the whole body to 1 gray of gamma- or X-rays. WebJun 14, 2024 · of Radiology (ACR) White Paper on Radiation Dose in Medicine places the final responsibility for additional action before radiation exposure on radiographers. Further, the paper states that “technologists are respon-sible for limiting radiation exposure to patients by ensuring that proper procedures and techniques are fol-lowed.”
WebBiological Effects of Radiation Whether the source of radiation is natural or man-made, whether it is a small dose of radiation or a large dose, there will be some biological effects. This chapter summarizes the short and long term consequences which may result from exposure to radiation.
WebSep 21, 2024 · If we assume the dose is equally distributed throughout the body, then the radiation dose per year is as follows: radiation dose per year = 2.87 × 10 − 2 J/yr 70.0 kg × 1 rad 1 × 10 − 2 J/kg = 4.10 × 10 − 2 rad/yr = 41 mrad/yr.
