Effective dose is a dose quantity in the International Commission on Radiological Protection (ICRP) system of radiological protection. [1]It is the tissue-weighted sum of the equivalent doses in all specified tissues and organs of the human body and represents the stochastic health risk to the whole body, which is the probability of cancer induction and genetic effects, of low levels of ...
The Total effective dose equivalent (TEDE) is a radiation dosimetry quantity defined by the US Nuclear Regulatory Commission to monitor and control human exposure to ionizing radiation. It is defined differently in the NRC regulations and NRC glossary.
"The calculation of the committed effective dose equivalent (CEDE) begins with the determination of the equivalent dose, H T, to a tissue or organ, T. Where D T ,R is the absorbed dose in rads (one gray, an SI unit, equals 100 rads) averaged over the tissue or organ, T, due to radiation type, R, and W R is the radiation weighting factor.
The radiation dose is determined from the intake using recommended dose coefficients". [25] A committed dose from an internal source is intended to carry the same effective risk as the same amount of equivalent dose applied uniformly to the whole body from an external source, or the same amount of effective dose applied to part of the body.
The effective dose refers to the radiation risk averaged over the entire body. [4] It is the sum of the equivalent dosage of all exposed organs or tissues. [4] Equivalent dose and effective dose are measured in sieverts (Sv). [4] Dose quantities used in radiation protection
The deterministic effects that can lead to acute radiation syndrome only occur in the case of high doses (> ~10 rad or > 0.1 Gy) and high dose rates (> ~10 rad/h or > 0.1 Gy/h). A model of deterministic risk would require different weighting factors (not yet established) than are used in the calculation of equivalent and effective dose.
The collective effective dose, dose quantity S, is calculated as the sum of all individual effective doses over the time period or during the operation being considered due to ionizing radiation. [ 1 ] : paragraph 159 It can be used to estimate the total health effects of a process or accidental release involving ionizing radiation to an ...
"The quantities equivalent dose and effective dose should not be used to quantify higher radiation doses or to make decisions on the need for any treatment related to tissue reactions [i.e., deterministic effects].
