The Bundesamt für Strahlenschutz (BfS) is the German Federal Office for Radiation Protection. The BfS was established in November 1989; the headquarters is located in Salzgitter, with branch offices in Berlin, Bonn, Freiburg, Gorleben, Oberschleißheim and Rendsburg. It has 708 employees (including 305 scientific) and an annual budget of around 305 million Euro (2009). Since 2009 the BfS is also responsible for the storage site of radioactive waste, Schacht Asse II.

Bornum am Elm is a village of 919 inhabitants (2021) in the city of Königslutter am Elm, Lower Saxony, Germany. It was a municipality until 1974, when it was joined to Königslutter. Bornum is near the northern edge of the Elm hills on the bank of the Scheppau stream, at an elevation of 135 meters. Neighboring places are Scheppau, Lauingen, and Abbenrode, as well as Königslutter proper. Industries include farming, tourism, and construction. Archaeological evidence shows the existence of the village in the Iron Age. The oldest documentary mentioning dates from 1135, when properties in Bornum were given to the newly founded Königslutter Abbey by Lothair III, Holy Roman Emperor. The manor of the village was given as a fief to various holders by the dukes of Brunswick-Lüneburg. In 1390, it came to the von Weferlingen family; they sold it to the von Westphalen family in 1764. In 1779, it was bought back by Charles I, Duke of Brunswick-Lüneburg, who sold it to Amelungsborn Abbey in 1781. Up to the Napoleonic period, the Lord of the Manor had jurisdiction over the village. In 1844 the manor was bought by the farmers in the village and was dissolved.

The Cremlingen transmitter is a large mediumwave transmission facility established in 1962 for transmitting the programme of Deutschlandfunk on 756 kHz near Cremlingen-Abbenrode. It was also known as Sender Braunschweig or Sender Königslutter. The first transmitter was installed in 1962. It transmitted the program of Deutschlandfunk on 755 kHz (756 kHz from 1978 on) at a power of 100 kW and used as its aerial a 137-metre-high guyed steel framework mast. The transmitter power was raised to 200 kW one year later, but it only operated during daytime for some time. Interferences with the Ravensburg mediumwave transmitter which worked on the same frequency were common.A second transmitter was installed for the transmission of the Deutschlandfunk programme on 548 kHz from 28 October 1963, initially with a power of 200 kW. It used a 240-metre-high guyed steel tube mast as its aerial, which was insulated against the ground, A second, insulated guyed steel framework mast was installed to shape the radiation pattern with a minimum towards the southeast, in order to avoid interferences with Radio Mayak in the Soviet Union. On 1 October 1967 the transmission power on 548 kHz was raised to 800 kW (400 kW during nighttime), sufficient to reach all of the northern Federal Republic of Germany and most of the territory of the GDR.According to the Geneva Frequency Plan of 1975 which came into effect in November 1978, transmissions on 548 kHz ceased in favour of Thurnau transmitter which started to transmit at this time on 549 kHz with 200 kW, and Nordkirchen transmitter on the same frequency with 100 kW. Both transmitters at Cremlingen were converted to combined operation at 756 kHz with a maximum daytime power of 800 kilowatts, and 200 kilowatts with a radiation minimum towards the southeast during the night. The height of the steel tube mast was reduced from 240 metres to 199 metres to optimize it for 756 kHz. Likewise, the steel framework mast used to for directional purposes was shortened to 99 m. The height of the 137-metre mast was not changed, it was used after 1978 as a backup aerial.The 800 kW vacuum tube transmitters have been dismantled, and since the middle of the 1990s the transmitter power has been 200 kW all day, provided by two 100 kW transmitters. In 2005, a fully transistorised and DRM capable 800 kW transmitter station was installed.From 2001 to 2003 the program of the pop music radio MEGARADIO was transmitted using the backup station on 630 kHz and the 137-metre-high radio mast as the aerial. This was made possible after this frequency, which had been used from 1978 until the mid-1990s for transmissions of SFB and NDR on 630 kHz from the Dannenberg transmitter in the daytime, had been re-coordinated for 24-hour transmission from the Cremlingen transmitter. From 1 April 2005 until 2 January 2013, the program of Voice of Russia was transmitted from Cremlingen on 630 kHz. Switch-off was planned for 31 December 2012, but a technical fault caused transmissions to continue until 2 January 2013.The last programme to be transmitted from this station was that of Deutschlandradio. Transmissions ceased on 31 December 2015. All masts have been demolished.

The Asse is a small hill range in the district of Wolfenbüttel in southeastern Lower Saxony with a median height of 200 metres ASL; the highest elevation is the Remlinger Herse with a height of 234 m. There are more than 600 different plants found here; the Asse is mostly covered by trees. It has been inhabited since the 6th millennium BC by farmers coming from the Danube region. For several hundred years, salt has been mined in Asse. One of these mines, Schacht Asse II, is now used to store low- and medium-grade radioactive waste produced by medicine and nuclear power plants.

The Asseburg is a ruined hill castle on the narrow, southern crest of the Asse ridge in the Harz Mountains of Germany, not far from Wolfenbüttel. The castle was built around 1218 by Gunzelin of Wolfenbüttel and his descendants of the House of Asseburg, as a so-called Ganerbenburg, or castle managed and occupied by more than one family or branch. Based on its dimensions, this elongated fortification was the largest hill castle in North Germany and was considered impregnable. Its purpose was to secure the lands around Wolfenbüttel. When Gunzelin refused to swear allegiance to Duke Albert I of Brunswick-Lüneburg, of the House of Welf, in 1255, the latter destroyed Gunzelin's Wolfenbüttel Castle and sieged Gunzelin's son Burchardus de Asseburc (Burchard or Busso of Asseburg) at Asseburg Castle. Burchard was able to withstand during three years, however in 1258 had to relinquish the castle to Duke Albert I. Burchard was then allowed to retreat to Westphalia with his knights, and received a compensation of 400 gold mark for the castle. After Gunzelin's death in 1260, his sons also lost the county of Peine to the bishop of Hildesheim. Asseburg became one of the strongest fortresses in the duchy. In 1330 the dukes had to pledge the castle to the city of Brunswick, which was interested in securing the trade routes below. When Duke Henry IV asked the castle back in 1492, threatening another siege, the garrison set fire on the castle and left. It fell into ruins after it was abandoned.

The Asse II mine (Schacht Asse II) is a former salt mine used as a deep geological repository for radioactive waste in the Asse Mountains of Wolfenbüttel, Lower Saxony, Germany.
