WebNov 6, 2024 · The study of rare fundamental physics phenomena, such as double-beta decay, rare nuclear decays and dark matter, requires very low levels of background radiation in order to observe a signal. To achieve the required background levels, experiments are located deep underground as these facilities provide significant rock overburden and … WebGermanium is more efficient than silicon for radiation detection due to its atomic number being much higher than silicon and lower average energy necessary to create an electron …
Is germanium radioactive
Did you know?
WebGermanium is a radioactive element. The most prevalent isotopes of germanium are Germanium 70, Germanium 72, Germanium 73, Germanium 74, and Germanium 76. … WebA Germanium detector spectrum showing the annihilation radiation peak (under the arrow). Note the width of the peak compared to the gamma ray peaks from radioactive decay visible in the spectrum. Annihilation radiation is not monoenergetic, unlike gamma rays produced by radioactive decay.
WebAug 6, 2024 · Since germanium is more resistant to damaging cosmic radiation than silicon, the solar cells’ lifespan can be extended from 15 to 20 years. “The main difference is that the solar cells are now germanium based instead of silicon based”, explains Bendix De Meulemeester, business development director at Umicore Electro-Optic Materials. WebGermanium is more efficient than silicon for radiation detection due to its atomic number being much higher than silicon and lower average energy necessary to create an electron-hole pair, which is 3.6 eV for silicon and 2.9 eV for germanium. This provides the latter with a better resolution in energy.
Germanium is insoluble in dilute acids and alkalis but dissolves slowly in hot concentrated sulfuric and nitric acids and reacts violently with molten alkalis to produce germanates ([GeO 3] 2−). Germanium occurs mostly in the oxidation state +4 although many +2 compounds are known. See more Germanium is a chemical element with the symbol Ge and atomic number 32.
