Product Description
BGO (bismuth germanate) is a scintillation crystal made of bismuth oxide and germanium oxide. It has a relatively high density and high atomic number, making it ideal for detecting high-energy photons. BGO scintillators have good energy resolution and high light output, which makes them useful for detecting gamma rays and other types of ionizing radiation.
Some Common Applications of BGO Crystals Include
1. Medical imaging: BGO scintillators are often used in positron emission tomography (PET) scanners to detect gamma rays emitted by radioisotopes in the body. They have excellent energy resolution and sensitivity compared to other scintillators used in PET imaging.
2. High-energy physics experiments: BGO crystals are used in particle physics experiments to detect high-energy photons and, in some cases, electrons and positrons. They are particularly useful for detecting gamma rays in the energy range of 1-10 MeV.
3. Security inspection: BGO detectors are often used in security inspection equipment such as luggage and cargo scanners to detect the presence of radioactive substances.
4. Nuclear physics research: BGO crystals are used in nuclear physics experiments to measure the gamma ray spectrum emitted by nuclear reactions.
5. Environmental monitoring: BGO detectors are used in environmental monitoring applications to detect gamma radiation from natural sources such as rocks, soil, and building materials.
