Committed Effective Dose Equivalent ( CEDE ) refers to the dose resulting from internal radiation exposures.
2.
The name " effective dose " replaced the name " effective dose equivalent " in 1991.
3.
The CEDE is combined with the Deep-Dose Equivalent ( DDE ), the dose from external whole body exposures, to produce the Total Effective Dose Equivalent ( TEDE ), the dose resulting from internal and external radiation exposures.
4.
The concept of "'effective dose "'was developed by Wolfgang Jacobi and published in 1975, and was so convincing that the ICRP incorporated it into their 1977 general recommendations ( publication 26 ) as " effective dose equivalent ".
5.
"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.
