Results. Effective dose calculations account for that by multiplying the absorbed radiation by the coefficient of the seriousness of the impact of radiation on each type of tissue or organ. When determining values of coefficient for different organs, researchers weighed not only the overall cancer risk but also the duration and quality of life of the patient, once cancer is contracted. absorbed dose in Gy multiplied by Radiation Weighting Factor). With the intent of emphasizing the physics over the biology, the Dose Ranges Chart uses equivalent dose for most quantities, and absorbed dose for medical exposures.
Absorbed dose is defined as the amount of energy deposited by ionizing radiation in a substance. Absorbed dose is given the symbol D. The absorbed dose is usually measured in a unit called the gray (Gy), which is derived from the SI system. The non-SI unit rad is sometimes also used, predominantly in the USA. The rad is a unit of absorbed radiation dose, defined as 1 rad = 0.01 Gy = 0.01 J/kg. It was originally defined in CGS units in 1953 as the dose causing 100 ergs of energy to be absorbed by one gram of matter. Absorbed dose is defined as the amount of energy deposited by ionizing radiation in a substance.

If playback doesn't begin shortly, try Radiation absorbed dose and effective dose in the international system of units (SI system) for radiation measurement uses "gray" (Gy) and "sievert" (Sv), respectively. In the United States, radiation absorbed dose , effective dose, and exposure are sometimes measured and stated in units called rad , rem , or roentgen (R) .
In the historical system of dosimetry, exposure to 1 roentgen (R) of X-rays results in absorption of 1 rad [radiation-absorbed dose], which had the effect of 1 rem
7 Dec 2012 In the investigation of accidental radiation exposure, an estimation of the absorbed dose is needed. Estimates may be used for treatment
Radiation dose measures the amount of energy deposited in an irradiated compound. Radiation dose is measured in units of gray (Gy). 1 Gy = 1 joule absorbed
