Used for neutron flux monitoring and safety controls in reactor cores [1].
10B+n→7Li+αto the tenth power cap B plus n right arrow to the seventh power cap L i plus alpha boron counter tube
The inner wall of the tube is coated with a solid layer of boron-10 . These are often used as an alternative to Helium-3 ( 3Hecubed cap H e BF3cap B cap F sub 3 Used for neutron flux monitoring and safety controls
These reaction products ionize the gas inside the tube, creating an electrical pulse that can be measured to count neutron events [20, 34]. Types of Boron Counters These tubes are filled with BF3cap B cap F sub 3 boron counter tube
