What are Gamma Rays?
The Discovery of Gamma RaysGamma-rays were firstobserved in1900byFrenchchemistPaulVillardwhen he wasinvestigating radia-tionfrom radium, according totheARPANSA.A few years later,ErnestRutherfordproposed the name "gamma-rays," following theorder of alpha rays and beta rays — names givento other particles that are created during anuclear reaction — and the name stuck.
Where do Gamma Rays camefrom?Gamma-rays are produced primarily byfour different nuclear reactions: fusion, fission, alphadecay and gamma decay.They are produced by the hottest and most energeticobjects in the universe, such as neutron stars and pulsars,supernova explosions, and regions around black holes.
