eddy currentshow / hide

Electric current generated by induction in a conductible body.

effective doseshow / hide

The Effective dose considers the different sensitivity of organs and tissues forstochastic radiation effects. For this purpose the equivalent doses are weighted by tissue weighting factors. The weighting factors represent the relative contributions of the single organs and tissues to the total health detriment resulting from uniform irradiation of the whole body.The effective dose is sum of the the tissue-weighted equivalent doses in all specified organs and tissues of the body. It is weighted such that the sum of the tissue weighting factors is unity. The unit of effective dose is J/kg with the special name Sievert (Sv). In radiation protection practice usually fractions of the unit dose are used, e. g. Millisievert (mSv), Microsievert (µSv).

emplacement chambershow / hide

Cavity methodically produced through mining where radioactive waste has been emplaced.

energy doseshow / hide

Absorbed energy of ionising radiation per unit of measurement. The unit of measurement is the gray (Gy)(1Gy = 1J/kg).

epicentreshow / hide

Projection of the focus of an earthquake area to the earth’s surface.

exclusion criteriashow / hide

The exclusion criteria primarily relate to geological and mining processes in an area. If an exclusion criterion already exists according to Section 22 of the Site Selection Act, an area is not suitable for disposing of high-level radioactive waste. The exclusion criteria include large-scale vertical movements, active fault zones, negative effects from mining operations, seismic activity, volcanic activity and the average retention times for groundwater.
