Identify the normally radioactive material in the following list. [#1066]

Plutonium is the only radioactive element in the list. Plutonium is a radioactive, silvery-gray, metallic element with the symbol Pu and atomic number 94. It has a high surface tension and viscosity compared to other metals, and tarnishes when exposed to air. Plutonium is created in a reactor when uranium atoms absorb neutrons, and is a by-product of nuclear power plants. It is the main fuel in fast neutron reactors, and more than one-third of the energy produced in most nuclear power plants comes from plutonium. Plutonium has five common isotopes, each with a different half-life, which is the time it takes to lose half of its radioactivity

Crust The structure of the Earth is divided into four major concentric layers: inner core, outer core, mantle and crust (the outermost layer). The crust is made up of tectonic plates, which are in constant motion.

Outer Core The magnetic field is generated by electric currents due to the motion of convection currents of a mixture of molten iron and nickel in Earth's outer core: these convection currents are caused by heat escaping from the core, a natural process called a geodynamo.

The lower fixed point in Fahrenheit scale is 32 degree and upper fixed point in Fahrenheit scale is 212 degree. The difference between the two is 180, hence number of division is 180.
