Effective follow-up dose

The effective subsequent dose is a factor in radiation protection . It is the effective dose that is accumulated as a result of the uptake of a radionuclide in the body ( incorporation ) over a period of time τ. The biological and physical half-life of the ingested nuclide are taken into account. The effective subsequent dose is denoted by E (τ), the unit is the sievert (Sv). A period of 50 years is assumed for adults. The corresponding effective subsequent dose is designated as E (50) or E ₅₀ . For children it is calculated up to the age of 70 years after incorporation.

The effective subsequent dose is calculated from the respective subsequent organ dose for all tissues and organs and the associated tissue weighting factors that are also used to determine the effective dose. The sizes are multiplied and summed over all tissues and organs T :

${\displaystyle E(\tau )=\sum _{\mathrm {T} }w_{\mathrm {T} }\cdot H_{\mathrm {T} }(\tau )}$.

The organ subsequent dose is the organ dose which is in the course of the time period τ in the respective organ or tissue accumulated.
