organ or tissue T and τ is the time elapsed after an 'intake' of <i>radioactive <br/>substances</i>. When τ is not specified, it will be taken to be 50 years for <br/>adults and the time to age 70 years for 'intakes' by children. (From <br/>Ref. [1].)<br/>

The unit of 'effective dose' is the 'sievert (Sv)', equal to 1 J/kg. The 'rem', equal to <br/>0.01 Sv, is sometimes used as a unit of 'equivalent dose' and 'effective dose'. This <br/>should not be used in 'IAEA publications', except when quoting directly from <br/>other publications, in which case the value in 'sieverts' should be added in <br/>parentheses.<br/>'Effective dose' is a measure of 'dose' designed to reflect the amount of <i>radiation <br/>detriment</i> likely to result from the 'dose'.<br/>Values of 'effective dose' from any type(s) of 'radiation' and mode(s) of <i>exposure<br/></i>can be compared directly.<br/>
