Totality of features of a sediment rock such as petrologic structure or fossil content.

Radioactive material from the atmosphere having reached the earth in the form of smallest particles and deposited through precipitation and sedimentation of aerosols, having for instance originated in nuclear tests.

From a certain distance to a radiation source on, the electromagnetic field is termed far field. In the far field the electric and magnetic field are closely coupled to each other and can be converted into each other using a constant factor.

Dividing surface in the rock where the adjoining rock strata are pushed together due to processes in the earth's interior (e.g. vertically displaced).

In a feasibility study it is investigated if and under which conditions a planned elaborate investigation can be successful.

Federal Network Agency for Electricity, Gas, Telecommunications, Post and Railways. In July 2005 the regulatory authority for telecommunications and post (RegTP) was renamed to "Federal Network Agency for Electricity, Gas, Telecommunications, Post and Railways". At the samt time its scope of duties was extended. The tasks in the area of telecommunications include e. g. the granting of site certific-ates for mobile phone base stations on the basis of the Ordinance concerning the Controls for the Limitation of Electromagnetic Fields (BEMFV). The Federal Network Agency carries out test series to control compliance with limit values as well as, in individual cases, controls of stationary amateur radio installations. Data of the site certificates of mobile phone base stations can be found in the EMF data base.

The Laender execute federal laws by order of the Federal Government (Bundesauftragsverwaltung, federal executive administration). When judging and deciding a situation differently, the Federal Government can give a federal order to the Land relating to the decision. The responsibility for the decision made according to the order is then with the Federal Government.

Federal state (or Laender) collecting depots are the interim storage facilities of the Laender erected for the waste produced in the areas of medicine, technology and research. Federal state collecting depots do not accept waste produced in connection with energy supply and reprocessing.

Sexual reproduction

State of space in which each space point can be assigned to the value of a physical quantity, e. g. electric or magnetic field strength.

Mass of all combustible materials in a defined room.

Nuclides generating by fission or the following radioactive decay of the nuclides that have directly generated by fission.

Worked, transported, deposited or enriched by rivers.

In Epidemiology, the follow-up is the observation of a group of persons (cohort) in a cohort study over a certain period of time (follow-up period). The cohort members are observed with respect to diseases (incidence follow-up) or death (mortality follow-up) by an appointed date. For the incidence follow-up, for example, cancer registries can be consulted. For deceased persons, the cause and date of death are requested at the health authorities and communities.

Interrelationship between organisms, where one link lives off the consumption of the previous link.

Unit of rocks belonging together genetically. Was formerly only used in terms of stratigraphics.

Aqueous solutions from the geological past stored in rock layers.

Number of oscillations in a time unit. Frequency and wavelength are connected to each other.

The measure of frequency is Hertz (Hz):
1 Hz = 1 oscillation per second = 1/s.
1 kilohertz (kHz) = 1000 Hz
1 megahertz (MHz) = 1000 kHz
1 gigahertz (GHz) = 1000 MHz
1 terahertz (THz) = 1000 GHz

Process where nuclear fuel supply of nuclear reactors and waste management is carried out, consisting of uranium mining, fuel enrichment, fuel element fabrication, reprocessing, fuel element storage and radioactive waste disposal.

Arrangement in which a multitude of fuel rods has been combined to form a construction unit with which the nuclear fuel is brought into the reactor.

Geometrical shape in which nuclear fuel, coated with hull material, is brought into a reactor. Mostly several fuel rods are combined to form a fuel element (Brennelement, BE). In the case of the Krümmel nuclear power plant with a boiling water reactor 72 fuel rods form a fuel element, in the case of the pressurised water reactor of the Emsland nuclear power plant 300 fuel rods have been combined to form one fuel element.
