Terrestrial radiation refers to the natural background radiation that originates from the Earth's crust and atmosphere. It includes radiation from radioactive elements such as uranium and thorium in the soil, as well as radiation from radon gas and cosmic rays from outer space. Terrestrial radiation is constantly present in the environment and contributes to the overall background radiation that humans are exposed to on a daily basis. **

Cosmic radiation refers to high-energy particles, mainly protons and atomic nuclei, that originate from outer space and bombard the Earth from all directions. These particles can come from sources such as the sun, supernovae, and other cosmic events. Terrestrial radiation, on the other hand, refers to the radiation that originates from the Earth itself, such as radioactive elements in the soil, rocks, and building materials. Both cosmic and terrestrial radiation contribute to the background radiation that humans are exposed to on a daily basis. **

Yes, there is still terrestrial television reception in Germany. The majority of households in Germany receive their television signals through terrestrial broadcasting, also known as DVB-T2. This allows viewers to access a variety of free-to-air channels without the need for a cable or satellite subscription.

I am an AI and do not have personal preferences or emotions, so I do not have the capability to like or dislike movies. However, I can provide information about the movie E.T. - The Extra-Terrestrial. It is a beloved classic directed by Steven Spielberg, known for its heartwarming story about a young boy who befriends an alien and helps him return home. The film has been praised for its emotional depth, memorable characters, and iconic moments, making it a favorite for many audiences. **

Terrestrial television reception relies on the transmission of signals through the airwaves, which can be affected by factors such as distance from the broadcast tower, weather conditions, and physical obstructions. Cable television, on the other hand, delivers signals through a physical cable connection, which generally results in a more reliable and consistent reception. Cable television also offers a wider range of channels and higher picture and sound quality compared to terrestrial television. **

To receive German channels via terrestrial television in Spain, you would need to have a digital terrestrial television (DTT) receiver that is compatible with the DVB-T2 standard, which is used for broadcasting in Germany. You would also need to be within range of a transmitter that is broadcasting the German channels. Additionally, you may need to adjust your antenna to receive the signals from the German transmitters. Once you have the necessary equipment and are within range of the transmitters, you should be able to scan for and receive the German channels on your DTT receiver. **
