No more than anything else. Almost all matter you encounter will contain small amounts of radioactive elements or isotopes. Granitic magma can contain small amounts of uranium, but not enough to pose any immediate danger. However, areas built on granitic bedrock can face a potential danger from radon.
Radioactive decay can generate heat within magma, contributing to its overall temperature. This heat can cause magma to become more fluid and less viscous, potentially leading to increased volcanic activity and eruptions. Additionally, radioactive decay products within magma can alter its chemical composition and influence its behavior.
Radioactive reactions in magma can be inferred through the presence of naturally occurring radioactive isotopes, such as uranium, thorium, and potassium-40 within the Earth's crust. Geochemical analyses of volcanic rocks often reveal elevated levels of these isotopes, indicating ongoing radioactive decay. Additionally, the heat generated from these radioactive processes can contribute to the melting of rocks and the formation of magma. Instruments that detect gamma radiation can also provide evidence of radioactive decay occurring in volcanic environments.
As soon as a mineral containing radioactive uranium crystallizes from magma, the uranium atoms become part of the solid mineral structure. This process effectively traps the uranium in a stable matrix, where it can undergo radioactive decay over time. The surrounding geological environment can influence the rate of decay and the potential for uranium to migrate or interact with surrounding materials. Additionally, the crystallization process can also lead to the formation of other minerals that may encapsulate or associate with the uranium, affecting its long-term stability and mobility.
The force that causes magma to erupt to the surface is primarily due to the build-up of pressure from the expansion of gases within the magma chamber. As the pressure exceeds the strength of the surrounding rock, the magma forces its way through the crust to reach the surface, resulting in an eruption.
The internal heat of the Earth is thought to be about 20% residual heat from planetary accretion and about 80% from radioactive decay. The internal heat provides heat to liquefy magma and send plumes of the hot material upward, through the mantle, to the surface. This material comes out from the surface in various forms, such as lava, and thus forms volcanoes.

Magma is propelled to the surface by temperature differences, which cause convection currents. The temperature differences result from radioactive elements within the mantle.
Their radioactive clock is set when they solidify from magma or lava.
Pressure and heat that produce magma are caused in part by the movement of tectonic plates deep within the Earth's mantle. This movement leads to the melting of rock at high temperatures and pressures, resulting in the formation of magma beneath the Earth's surface.
Because then, instead of a small volume of relatively concentrated radioactive material, what you get is a large volume of dilute radioactive material that you don't know the exact location of, which may still include relatively concentrated pockets. Dispersion is pretty much exactly what you do notwant to happen with radioactive waste, unless you can precisely control the dispersion and make sure that the concentration is everywhere negligible.
Geothermal energy is the heat from the Earth's interior. This heat originates from the original formation of the earth, radioactive decay and friction due to the tidal forces acting on the magma.
Sedimentary rock is not original source material, its rock that got ground into sand, settled (usually under water), got buried, and then got heated and squeezed back into a form of rock. Lots of sources.
