Gallery show / hide
A gallery is a horizontal or nearly horizontal mine opening for material transport, men-haulage and ventilation, which is long in proportion to the cross-cut.
Gamma dose rate show / hide
The gamma dose rate is the radiation exposure which effects man from outside. It is given as dose equivalent, measured at a certain place per hour. The gamma dose rate is generally given in Microsievert per hour (µSv/h).
Gamma measurementshow / hide
Measurement of the external radiation that humans are exposed to depending on time and place.
Gamma radiation show / hide
Electromagnetic wave radiation emitted by an atomic nucleus. Gamma radiation of the same physical nature as visible light, however with considerably more energy and high penetration capacity in matter. Heavy materials such as lead or concrete must therefore be used for shielding from gamma radiation. Apart from the type of generation gamma radiation can be compared to X-radiation.
Gamma submersion show / hide
Radiation exposure through gamma radiation of radioactive aerosols and gases in the atmosphere.
Gantry craneshow / hide
The gantry crane spans its working area like a bridge. It runs mostly on two parallel tracks upon which it supports itself. On account of its design the gantry crane can lift great loads between its supports.
Gastroenterology show / hide
Special area of internal medicine dealing with the diseases of the gastro-intestinal tract and adjacent organs.
geophoneshow / hide
A geophone works like a highly sensitive microphone. It converts slightest tremors of the ground into electrical signals.
Geosphere show / hide
Geosphere is the space where the earth's crust, water and air hull touch and penetrate each other.
Global System for Mobile Communications (GSM)show / hide
International standard for mobile communications operations. The transmission frequencies are at 900 MHz (e. g. D-network) and 1800 MHz (e. g. E-network). The data transmission rate is 9.6 kbit/s. The signal is pulsed with 217 Hz.
Gon show / hide
A measure usual in geodesics of the even angle, defined as the hundredth part of the right angle ( 1 Gon = 0,9°).
Gray show / hide
SI-measure of the energy dose, 1 Gray (Gy) = 1 joule per kilogram.
Guide railshow / hide
Guide rail for the winding conveyance, such as the cage or basket.
