Approximately 80% of the Earth's natural radioactivity comes from the decay of uranium, thorium, and potassium-40 in the Earth's crust.
There are two radioactive alkaline earth metals: radium (Ra) and radium (Ra). Both elements have radioactive isotopes that undergo radioactive decay.
Barium is the heaviest non-radioactive alkali Earth metal, with an atomic number of 56.
Yes, Earth does have radioactive internal energy, which comes from the decay of radioactive elements in its core. As for external energy, Earth receives energy from the Sun in the form of solar radiation, which affects various processes on the planet such as weather patterns and climate.
The main sources of heat in the Earth's interior are residual heat from the planet's formation, radioactive decay of elements like uranium, thorium, and potassium, and heat generated by ongoing processes like mantle convection and core formation. This heat leads to processes like plate tectonics, volcanic activity, and the Earth's magnetic field.
The source of heat in the mantle primarily comes from the decay of radioactive elements like uranium, thorium, and potassium. This process releases energy in the form of heat which contributes to the high temperatures within the Earth's mantle.
Radium is the radioactive metal among alkaline earth metals.

The core of the earth is radioactive, as is the sun. Granites, which crystallize from mantle material are commonly slightly radioactive.
Americium can be a radioactive contaminant of the earth.
Barium is the heaviest non-radioactive alkali Earth metal, with an atomic number of 56.
it can kill the earth and even us if there is to much
One half-life has passed for 50 percent of the original radioactive material to decay.
The time it takes for 50 percent of the nuclei in a radioactive sample to decay to its stable isotope is called the half-life of the radioactive element. It is a characteristic property of each radioactive isotope and can vary greatly among different elements.
Radioactive Decay
Underground - from radioactive decay.
Radium. Elements with an atomic number greater than 83 are always radioactive.
