H3, Deuterium is radioactive. Uranium and plutonium are radioactive and are used in atomic bombs.
Uranium is a dense, silvery-white metal that is weakly radioactive. In its natural state, it has a metallic luster and can also appear as a black oxide when exposed to air. It is primarily used in nuclear reactors and weapons.
discovered polonium discovered the existence of radium found how to isolate the radium metal discovered that thorium was a radioactive element discovered that uranium rays give conductivity to the air surrounding them
It's a semantic thing - by definition, if something gives out radiation, then it is radioactive. If an element gives off radiation, then it is a 'radioactive' element. If it does not give out radiation, then it is not 'radioactive'.
Well you could eat uranium or other or radioactive waste... But as Uranium is expensive and rare, and radioactive waste is deadly, eating radiation would result in killing you. This will not give you super powers like shown in cartoons, but it will end up with you receiving radiation poisoning.

Radioactive elements give off atomic energy by spontaneous decay.Fissionable elements give off atomic energy by fissioning when struck by neutrons.Fusible elements give off atomic energy by thermonuclear fusion at very high temperature and pressure.
name and give the symbol of 2 radio active elements
the unstable elements in periodic table is Radium because it always leave the radio active waves so it lost its mass slowly slowly all radio active elements are unstable. Any thing more By Varun
Quartz itself does not give off radiation. However, certain impurities or inclusions within quartz crystals can make them weakly radioactive. These radioactive elements include uranium, thorium, and potassium.
Various radioactive substances such as Plutonium and Uranium give off a combination of alpha, beta and gamma rays as the isotope decays.
Elements that can give off small particles include radioactive elements like uranium and radium, as well as elements in the form of nanoparticles such as gold, silver, and iron. These small particles can be released into the environment through processes like radioactive decay or as byproducts of industrial activities.
