Dose conversion coefficient
The quantity dose conversion coefficient e(50) (in Sv·Bq-1) makes it possible to convert becquerel (Bq) to sievert (Sv) in the case of irradiation by internal activity:E(50) = e(50) × A
Here, E(50 is the committed effective dose (in Sv) due to the intake of activity A (in Bq).
The value of the dose conversion coefficient strongly depends on the nuclide, the chemical properties of the radioactive substance, and the method of intake.
